0:01:38 > 0:01:42I'll be dishing them out over three slamming rounds of popocity,
0:01:42 > 0:01:46where I meet the people who knew the stars back in the day.

0:02:06 > 0:02:09I love his songs and the way he sings.
0:02:09 > 0:02:11His music is honestly just amazing.
0:02:11 > 0:02:13Go Sam Smith!
0:02:13 > 0:02:16I'm on the team of Selena Gomez, cos she's a really good singer
0:02:16 > 0:02:18and her songs are always bright and different.
0:02:18 > 0:02:22I love most of her films and I love all her music.
0:02:22 > 0:02:25Go, Team Selena Gomez, pop!
0:02:25 > 0:02:27It's going to be so close. I mean, Sam is pretty much
0:02:27 > 0:02:30one of the hottest things in pop music right now.
0:02:30 > 0:02:32And then, there's Little Miss Gomez, who can sing, act,
0:02:32 > 0:02:34and travels the world with her music.
0:02:34 > 0:02:36Who do you think's going to win?
0:02:36 > 0:02:38There's only one way to find out.
0:02:38 > 0:02:40It's time for Pop Slam!
0:02:45 > 0:02:47Round one, Pop Potential.
0:02:47 > 0:02:50This is all about how our stars made it big.
0:02:50 > 0:02:52First up, Sam Smith.
0:02:52 > 0:02:55# I don't have money on my mind
0:02:55 > 0:02:57# Money on my mind
0:02:57 > 0:02:59# I do it for I do it for the love. #
0:02:59 > 0:03:04Sam is hands down one of the hottest singers in the world right now.
0:03:04 > 0:03:06But before he scaled the heights of pop stardom,
0:03:06 > 0:03:11he grew up here - in the village of Great Chishill, in Cambridgeshire!
0:03:11 > 0:03:14# I do it for I do it for the love
0:03:14 > 0:03:17# I don't have money on my mind...#
0:03:17 > 0:03:20This is the very street where Samuel Frederick Smith grew up.
0:03:20 > 0:03:22Back in the day, he'd walk around
0:03:22 > 0:03:25listening to his music, singing along.
0:03:25 > 0:03:27Little did he know that one day
0:03:27 > 0:03:30his voice would be listened to all over the world.
0:03:30 > 0:03:32Here's how it all happened.
0:03:32 > 0:03:35MUSIC: Like I Can by Sam Smith
0:03:35 > 0:03:37# There may be lovers who hold out their hands but
0:03:37 > 0:03:42# They'll never love you like I can can can. #
0:03:42 > 0:03:45The village that Sam grew up in is really small -
0:03:45 > 0:03:48so small that everyone pretty much knows everyone.
0:03:48 > 0:03:51I mean, I've been here five minutes and I know everyone.
0:03:51 > 0:03:52Hey, Rebecca!
0:03:55 > 0:03:57Chazza, Andy, Keith!
0:03:57 > 0:03:59- Hi, Amberley!- All right.
0:04:00 > 0:04:02AMBERLEY WHISTLES
0:04:02 > 0:04:04- Carl, Oli?- All right, mate?
0:04:04 > 0:04:06Hey, two hands!
0:04:06 > 0:04:08MUSIC: Leave Your Lover by Sam Smith
0:04:08 > 0:04:10# Pack up and leave everything
0:04:10 > 0:04:13# Don't you see what I can bring?
0:04:13 > 0:04:19# Can't keep this beating heart at bay. #
0:04:21 > 0:04:24Back when Sam was 12, it was clear that he could sing,
0:04:24 > 0:04:27so he decided to take his voice to the next level
0:04:27 > 0:04:29and join the Cantate Youth Choir.
0:04:29 > 0:04:33Check this out. This is the school where they used to rehearse.
0:04:33 > 0:04:35# Leave your lover
0:04:37 > 0:04:39# Leave him for me. #
0:04:40 > 0:04:43The Cantate Youth Choir is one of the most successful
0:04:43 > 0:04:45youth choirs in the UK.
0:04:45 > 0:04:47Sam, you can have two Ambo points
0:04:47 > 0:04:50for getting some early singing experience.
0:04:50 > 0:04:53# Leave him for me. #
0:04:55 > 0:04:58In the choir, Sam's voice was getting bigger,
0:04:58 > 0:05:01but it was outside the choir that Sam would meet someone
0:05:01 > 0:05:04who would help him craft a voice that would wow the world.
0:05:04 > 0:05:08That was singing coach Joanna Eden and I'm off to get all the goss.
0:05:09 > 0:05:13The choir was great, but Sam needed some one-on-one training
0:05:13 > 0:05:16and Joanna was on hand to help take his voice to the next level.
0:05:18 > 0:05:22- Joanna!- Hey, nice to see you. - Lovely to see you.
0:05:22 > 0:05:25What was a nine-year-old Sam like?
0:05:25 > 0:05:30He was very sweet, very polite - a really nice boy,
0:05:30 > 0:05:32and I thought, he's probably going to be shy about singing.
0:05:32 > 0:05:36But he opened his voice and it was so relaxed and so confident.
0:05:36 > 0:05:39He would just sort of fly up to a high note with no fear,
0:05:39 > 0:05:41which is quite rare in children.
0:05:41 > 0:05:43So was Sam writing songs all the way back then?
0:05:43 > 0:05:48No, not at 9. When he got to about 17, his mum rang me up and said,
0:05:48 > 0:05:50"Sam wants to come and make some demos with you."
0:05:50 > 0:05:53He came along and the first song he brought me was called
0:05:53 > 0:05:57Hold On Tight and it was just the perfect little pop song.
0:05:57 > 0:05:59Well, Joanna, thank you so much. It has been a pleasure.
0:05:59 > 0:06:03One more time, give me another hug. Aw, yes!
0:06:03 > 0:06:04MUSIC: Restart by Sam Smith
0:06:04 > 0:06:09# It was a Monday night and you told me it was over, babe. #
0:06:09 > 0:06:14For writing great songs at the age of 17, have two Ambo Points, Sam.
0:06:14 > 0:06:17# I knew that I would be OK. #
0:06:17 > 0:06:18Sam's talent was growing,
0:06:18 > 0:06:20but his hometown wasn't getting any bigger.
0:06:20 > 0:06:22Time for a change.
0:06:25 > 0:06:30And when he turned 18, he moved here to London, to make it as a singer.
0:06:30 > 0:06:32But it's never that easy, is it?
0:06:32 > 0:06:36# When I'm the one playing the fool. #
0:06:37 > 0:06:40In fact, to make ends meet, Sam got a job in a pub,
0:06:40 > 0:06:44where he had to clean the loos.
0:06:44 > 0:06:46When he wasn't scrubbing the dunny,
0:06:46 > 0:06:48Sam would go check out gigs in London.
0:06:48 > 0:06:50And it was at an Adele gig
0:06:50 > 0:06:54where he got his foot in the door, by putting his foot in his mouth.
0:06:54 > 0:06:58# The truth is I'm better on my own. #
0:06:58 > 0:07:01The story goes that whilst Sam was at an Adele gig,
0:07:01 > 0:07:06he heckled one of the support acts, a guy called Elvin Smith.
0:07:06 > 0:07:11Heckling is a bit naughty and our Sam felt pretty bad about it.
0:07:11 > 0:07:14So, he got in contact with Elvin online to say sorry.
0:07:14 > 0:07:19A few years later, they met again and Sam sent him one of his songs.
0:07:19 > 0:07:21Elvin put him in contact with a producer, who in turn
0:07:21 > 0:07:24put him in contact with a little-known music duo -
0:07:24 > 0:07:26Disclosure!
0:07:26 > 0:07:29MUSIC: White Noise by Disclosure feat AlunaGeorge
0:07:29 > 0:07:31The Disclosure boys may be huge now,
0:07:31 > 0:07:36but back in 2012 they were just two lads on the trail of pop stardom
0:07:36 > 0:07:40and they were working on the future mega-hit called Latch.
0:07:40 > 0:07:43Latch wasn't meant to have any singing on it, but Sam asked
0:07:43 > 0:07:46the Disclosure boys if he could write some words for the song.
0:07:46 > 0:07:49They loved his voice, so they agreed.
0:07:49 > 0:07:52Nice choice boys, because the song went on to be huge!
0:07:52 > 0:07:56# Now I've got you in my space...
0:07:56 > 0:07:58# I won't let go of you. #
0:08:01 > 0:08:05Sam, have four Ambo Points for helping to create a massive hit
0:08:05 > 0:08:08with your buddies, Disclosure. Tune!
0:08:08 > 0:08:12# Now I've got you in my space
0:08:12 > 0:08:15# I won't let go of you. #
0:08:15 > 0:08:16The UK had been introduced
0:08:16 > 0:08:19to the Cambridgeshire choirboy's unforgettable voice,
0:08:19 > 0:08:23and soon he would become a household name all around the world.
0:08:23 > 0:08:27# Got you shackled in my embrace
0:08:27 > 0:08:30# I'm latching onto you. #
0:08:30 > 0:08:33That's how Sam LATCHED onto stardom.
0:08:33 > 0:08:37Now, let's head across the Atlantic to find out how Selena made it.
0:08:37 > 0:08:39MUSIC: Slow Down by Selena Gomez
0:08:39 > 0:08:41# Now that I have captured your attention
0:08:41 > 0:08:46# I wanna steal ya for a rhythm intervention... #
0:08:46 > 0:08:49Selena Gomez is the super-talented singing sensation
0:08:49 > 0:08:52who's had hits all over the globe.
0:08:52 > 0:08:55But before all that, she was a cheeky little girl,
0:08:55 > 0:08:59living right here in Dallas, Texas!
0:08:59 > 0:09:02# Cos I just wanna party all night in the neon lights
0:09:02 > 0:09:04# Till you can't let me go. #
0:09:04 > 0:09:07Selena Marie Gomez was born in 1992 -
0:09:07 > 0:09:09the same year as Sam Smith -
0:09:09 > 0:09:12and she lived on this very street.
0:09:12 > 0:09:15Back when Selena was a kid, money was pretty tight
0:09:15 > 0:09:18and her mum had to work three jobs to provide for her.
0:09:18 > 0:09:22This is the story of how Miss Gomez went from a Texan girl
0:09:22 > 0:09:25to one of the biggest superstars in the world.
0:09:25 > 0:09:28# Yeah, baby, slow down the song
0:09:28 > 0:09:31# Oh oh oh oh
0:09:31 > 0:09:34# Yeah, baby, slow down the song. #
0:09:34 > 0:09:37Selena used to watch her mum act in local theatre
0:09:37 > 0:09:40and that inspired her to become an actress.
0:09:40 > 0:09:44And in 1999 she got her first big audition.

0:11:18 > 0:11:20this time with Disney!
0:11:20 > 0:11:24And this is footage of Selena auditioning back in 2004.
0:11:24 > 0:11:27Um, I'm trying to get into my singing career and my acting career, so...
0:11:27 > 0:11:30- You can sing too?- Yeah. I want to do that when I get older.
0:11:30 > 0:11:33- I want to be both. - Were you born here in Austin?
0:11:33 > 0:11:36No, I was born in Grand Prairie, Texas, in Dallas.
0:11:36 > 0:11:38MUSIC: Music Feels Better by Selena Gomez
0:11:38 > 0:11:41I want to know everything I can about Selena back then,
0:11:41 > 0:11:43so I've come to meet Cathryn Sullivan,
0:11:43 > 0:11:45her acting coach from back in the day,
0:11:45 > 0:11:47to find out more about her awesome skills.
0:11:50 > 0:11:51Tricky door.
0:11:53 > 0:11:56Cathy is an acting coach with a bucket-load of experience.
0:11:56 > 0:12:00She's taught loads of people, including Selena's old mate, Demi.
0:12:01 > 0:12:05- Hi.- How are you?- I'm good.
0:12:05 > 0:12:07Thank you so much for having me.
0:12:07 > 0:12:11So, Cathryn, you used to coach Selena. Is she that good an actress?
0:12:11 > 0:12:15- Yes! Yes, she is. - What is it about her?
0:12:15 > 0:12:20Even at nine years old, she had, like, this work ethic.
0:12:20 > 0:12:22Every time she got a pilot, she prepared fabulously.
0:12:22 > 0:12:24She would come over and we'd sit there
0:12:24 > 0:12:27and she'd go over every single page of the pilot,
0:12:27 > 0:12:30so that when she went on set, she would be prepared.
0:12:30 > 0:12:32One thing that a lot of people don't know about Selena
0:12:32 > 0:12:36and her family - she really is a rags-to-riches kind of story,
0:12:36 > 0:12:38because her family didn't have a lot of money back then.
0:12:38 > 0:12:42Her mother would drive the car over and give me 25 cheques,
0:12:42 > 0:12:45and once in a while they'd try to pay for it.
0:12:45 > 0:12:46You could tell she had talent.
0:12:46 > 0:12:48She was a really good student,
0:12:48 > 0:12:50so she picked up on things really quickly.
0:12:50 > 0:12:52I didn't know she was going to be this much,
0:12:52 > 0:12:54but I knew she was going to work.
0:12:54 > 0:12:58# The music feels better with you. #
0:12:58 > 0:13:01With Cathy's training, Selena's acting got even better
0:13:01 > 0:13:05and, in 2007, all the hard work paid off big-time,
0:13:05 > 0:13:08when she got the biggest role of her career -
0:13:08 > 0:13:12Alex Russo in Wizards Of Waverly Place. Boom!
0:13:13 > 0:13:16MUSIC: Magic by Selena Gomez

0:13:28 > 0:13:31but how did she become a massive pop star?
0:13:31 > 0:13:35Well, in 2009, Disney released a Wizards Of Waverley Place album.
0:13:35 > 0:13:40Selena sang the show's theme tune and this bad boy.

0:13:45 > 0:13:47Selena, have two Ambo Points
0:13:47 > 0:13:50for unveiling your awesome voice to the world.
0:13:52 > 0:13:54The world had finally been introduced
0:13:54 > 0:13:55to Selena's singing skills.
0:13:55 > 0:13:59But she didn't want to be any old pop princess.
0:13:59 > 0:14:02Selena loved bands like Paramore and Fall Out Boy
0:14:02 > 0:14:05and wanted to follow in their footsteps.
0:14:05 > 0:14:07So, in 2008,

0:14:27 > 0:14:32Selena smashed into the US charts in 2010 with Naturally.
0:14:32 > 0:14:36And NATURALLY, the US folks loved it.
0:14:36 > 0:14:39But Selena wanted more than just America.
0:14:39 > 0:14:41Next up, the world!
0:14:41 > 0:14:44# Everything comes naturally

0:15:37 > 0:15:40had him knocking on the doors of pop stardom,

0:16:34 > 0:16:37the epic Stay With Me.
0:16:37 > 0:16:41That's three quickfire number one hits in just one year.
0:16:41 > 0:16:44Sam, have three Ambo Points, you legend.
0:16:48 > 0:16:51Check out this little snippet of pop goss.
0:16:51 > 0:16:53On the chorus of Stay With Me,
0:16:53 > 0:16:56it sounds like there's a choir singing behind Sam's voice.
0:16:56 > 0:17:01# Oh, won't you stay with me? #
0:17:01 > 0:17:03That's no choir, people.
0:17:03 > 0:17:08That is 20 takes of Sam's voice, layered on top of each other.
0:17:08 > 0:17:1120 Sams for the price of one. That's a good deal.
0:17:11 > 0:17:13# It's clear to see
0:17:13 > 0:17:17# But darling stay with me. #
0:17:19 > 0:17:22Making a full choir out of just one voice

0:17:32 > 0:17:34# Lose yourself tonight... #
0:17:34 > 0:17:37Once Selena Gomez & The Scene hit the scene,
0:17:37 > 0:17:41they released an album every year for three years.

0:18:14 > 0:18:17In 2012, and after four years with the band,
0:18:17 > 0:18:19Selena decided to go solo.
0:18:19 > 0:18:22A brave move, but it paid off big-time.
0:18:22 > 0:18:25Her debut single Come & Get It gave her
0:18:25 > 0:18:28her first top ten hit right here in the UK.
0:18:28 > 0:18:29Go, girl!

0:18:39 > 0:18:43She also received an MTV award for Best Pop Video.

0:18:47 > 0:18:51Have another two Ambo Points for making an award-winning vid.
0:18:53 > 0:18:57And Selena's not the only one with an award on her mantelpiece.
0:18:57 > 0:18:59What's the biggest accolade you can receive
0:18:59 > 0:19:01if you're an up-and-coming pop star?
0:19:01 > 0:19:05How about the BBC Sound of 2014?
0:19:05 > 0:19:09Previous winners have included Adele, Ellie Goulding and Jessie J.
0:19:09 > 0:19:14# I'm so encaptured Got me wrapped up in your love... #

0:19:20 > 0:19:22# Feel so enamoured
0:19:22 > 0:19:27# Hold me tight within your clutch. #
0:19:27 > 0:19:30But Sam wasn't just happy with cracking the UK.
0:19:30 > 0:19:33Oh, no. This guy wanted world domination -
0:19:33 > 0:19:35and it all started when he performed
0:19:35 > 0:19:38on one of the biggest TV shows in the US -
0:19:38 > 0:19:40Saturday Night Live.
0:19:40 > 0:19:45# Can I lay by your side
0:19:48 > 0:19:52# Next to you? #
0:19:52 > 0:19:58As if this wasn't impressive enough, Sam was the only artist in the world
0:19:58 > 0:20:03to sell one million albums in both the UK and USA in 2014.
0:20:03 > 0:20:06And his takeover of America was complete
0:20:06 > 0:20:11when he won four Grammys in 2015.
0:20:11 > 0:20:13The Grammys are the biggest awards in pop
0:20:13 > 0:20:17and artists dream of winning one, never mind four!
0:20:17 > 0:20:20That's got to be five Ambo points.
0:20:20 > 0:20:24And Sam's not the only one working hard to get his music out there.
0:20:24 > 0:20:26MUSIC: Love You Like A Love Song Baby by Selena Gomez
0:20:26 > 0:20:28# I, I love you like a love song, baby
0:20:28 > 0:20:32# I, I love you like a love song, baby... #
0:20:32 > 0:20:36Selena Gomez loves a bit of globe-trotting too.
0:20:36 > 0:20:40# And I keep hittin' re-peat-peat-peat-peat-peat. #
0:20:40 > 0:20:44In 2013, she went on a massive tour all around the world,
0:20:44 > 0:20:50hitting 15 countries and doing a whopping 57 shows!
0:20:50 > 0:20:52Wow, this girl!
0:20:53 > 0:20:55CHEERING
0:20:57 > 0:21:00Miss Gomez works her socks off to keep her fans happy.
0:21:02 > 0:21:06Before every gig, she tries to meet as many fans as possible
0:21:06 > 0:21:09and her family and friends will grab a bunch of peeps
0:21:09 > 0:21:11to come and meet her backstage.
0:21:11 > 0:21:15Have four Ambo Points for being BFFs with your fans, Selena.
0:21:17 > 0:21:20And it's not just Selena Gomez who gives it all for her fans.
0:21:20 > 0:21:25# Oh, baby, oh, baby We both know the truth... #
0:21:27 > 0:21:30Sam's live performances are pretty special too.
0:21:30 > 0:21:34When Sam's performing, he brings some serious emotion to the stage.
0:21:34 > 0:21:37But sometimes he can go a little bit too far -
0:21:37 > 0:21:39like this one time at a gig in New York.
0:21:39 > 0:21:40Now, I wasn't there,
0:21:40 > 0:21:42but I imagine it went down a little bit like this...
0:21:44 > 0:21:48Hi, everyone. My name is Sam Smith and this actually my last tune.
0:21:48 > 0:21:51It's called Leave Your Lover, and, just as a warning,
0:21:51 > 0:21:52it might get a little bit emotional.
0:21:52 > 0:21:55Let's get in the zone. Let's think some sad thoughts.
0:21:55 > 0:21:58Ooh, I've got one. OK, so you've bought some ice cream
0:21:58 > 0:22:00and you've dropped a chocolate flavour on the ground.
0:22:00 > 0:22:04Ooh, that's sad. Sad, sad, sad. OK, need some more, need some more.
0:22:04 > 0:22:06Ooh, I've got it. You bought a balloon and you've let it go
0:22:06 > 0:22:09and you're watching it fly away. Ooh! Sad, sad, sad.
0:22:09 > 0:22:11Oh...
0:22:11 > 0:22:12I'm already in the zone.
0:22:12 > 0:22:15You've bought a toy and then you've got home and you realise
0:22:15 > 0:22:17you have no batteries and the shops are closed!
0:22:17 > 0:22:20- So sad! - SHE SOBS
0:22:20 > 0:22:22Oh, no - sad, sad!
0:22:25 > 0:22:28That's right. Apparently, Sam got a little too emotional
0:22:28 > 0:22:31at one of his gigs and he actually started crying.
0:22:31 > 0:22:38# Will you take me to nirvana? #
0:22:38 > 0:22:43Actually, it was only a tear or two Sam shed that night,
0:22:43 > 0:22:45but for getting in the zone with your music,
0:22:45 > 0:22:48have three Ambo Points, Mr Smith.
0:22:48 > 0:22:51And that's round two done. Let's take a look at the scores.
0:22:53 > 0:22:55This is a mega close one,
0:22:55 > 0:22:59but Sam's pop success has taken him into the lead.
0:22:59 > 0:23:01If you don't agree with me,
0:23:01 > 0:23:04then get onto the CBBC website and have your say!
0:23:05 > 0:23:08We've found out how our pop royalty made it big,
0:23:08 > 0:23:10and how successful they've been.
0:23:10 > 0:23:13It's now time to see how glam they've become in round three.
0:23:18 > 0:23:20Round three, Pop Style.
0:23:20 > 0:23:23This is all about our celebrities' lives.
0:23:23 > 0:23:26Clothes, cars, pets or whatever else they splash their cash on.
0:23:26 > 0:23:28First up, Selena Gomez.
0:23:28 > 0:23:30# Round and round
0:23:30 > 0:23:32# We're never gonna stop
0:23:32 > 0:23:34# Always round and round
0:23:34 > 0:23:36# We'll never get where we're going. #
0:23:36 > 0:23:39When it comes to fashion, Selena Gomez is off the hook
0:23:39 > 0:23:41and she can rock a variety of looks.
0:23:44 > 0:23:48She looks great when working the classic Hollywood style...
0:23:50 > 0:23:52..and she looks fantastic as a rock chick.
0:23:57 > 0:24:00She even looks fab when dressed as a spy.
0:24:04 > 0:24:09Let's face it, this girl can wear anything and look fantastic.
0:24:09 > 0:24:13Miss Gomez, I'm awarding you four Ambo Points for your amazing style.
0:24:17 > 0:24:19But she's not the only one
0:24:19 > 0:24:21who knows how to rock a trendy outfit or two.
0:24:21 > 0:24:23Sam is a fan of the classic look
0:24:23 > 0:24:27and, if I do say so myself, I think he scrubs up pretty well.
0:24:27 > 0:24:31# And they say I'm crazy
0:24:33 > 0:24:38# Cos you don't think I know what you've done. #
0:24:40 > 0:24:42Sam Smith's voice is so clean and it's so lovely
0:24:42 > 0:24:44and it's so heartfelt.
0:24:44 > 0:24:47I think the way that he dresses almost...
0:24:47 > 0:24:49I don't know, maybe it takes less attention away from him
0:24:49 > 0:24:51and puts the focus on the music.
0:24:51 > 0:24:55# I know I'm not the only one... #
0:24:56 > 0:25:01Sam, have one Ambo Point for your smart, down-to-earth wardrobe.
0:25:01 > 0:25:04Both of these guys know how to rock a stylish look,
0:25:04 > 0:25:06but how do they get around town?
0:25:08 > 0:25:11Selena Gomez may be a multi-millionaire
0:25:11 > 0:25:14Hollywood superstar and she probably has her fair share of flashy cars,
0:25:14 > 0:25:18but this Texan girl loves nothing more than riding a quad bike.
0:25:18 > 0:25:21MUSIC: Falling Down by Selena Gomez & The Scene
0:25:23 > 0:25:26Selena, you can have two Ambo Points for rocking the quad
0:25:26 > 0:25:28and burning some rubber.
0:25:30 > 0:25:32When she's not tearing up the back yard,
0:25:32 > 0:25:34Selena loves hanging out with her dogs.
0:25:34 > 0:25:38And she's adopted not one, but six rescue dogs!
0:25:38 > 0:25:40Yes, six.
0:25:40 > 0:25:44I'm giving you three Ambo Points for all those walkies.
0:25:44 > 0:25:48And hey, it's not just Selena's dogs who like a good stroll.
0:25:48 > 0:25:50Sam loves to walk.
0:25:50 > 0:25:53It's where he gets inspiration for a lot of his songs.
0:25:53 > 0:25:55In fact, he wrote the lyrics to La La La
0:25:55 > 0:25:59whilst walking home from work by the River Thames in London.
0:26:02 > 0:26:05Sam, have three Ambo Points for mixing exercise
0:26:05 > 0:26:07with genius songwriting skills.
0:26:10 > 0:26:13Sam loves to write songs when he's strolling,
0:26:13 > 0:26:17but he'll sing them anywhere, including the shower.
0:26:17 > 0:26:20MUFFLED SINGING
0:26:22 > 0:26:25This is actually him singing in the shower.
0:26:28 > 0:26:30See? Sam's no different to you and me.
0:26:30 > 0:26:34Mr Smith, take two Ambo Points for staying in tune
0:26:34 > 0:26:36even when you're washing your hair.
0:26:36 > 0:26:39And that, my friends, is the end of round three.
0:26:43 > 0:26:45Well, it's been quite a journey, hey, guys?
0:26:45 > 0:26:48But it's time we got a little bit serious.
0:26:48 > 0:26:51And the winner of the Ambo will be revealed
0:26:51 > 0:26:53straight after we take a look back at what we've learnt.
0:26:55 > 0:26:58It's been a battle of Sam's stunning vocals
0:26:58 > 0:27:01versus Selena's pop sass.
0:27:01 > 0:27:05Both have wowed the crowds on both sides of the Atlantic Ocean
0:27:05 > 0:27:08and have built up seriously big fan bases.
0:27:08 > 0:27:11This Pop Slam is too close to call.
0:27:12 > 0:27:16Ladies and gentlemen, the moment is finally upon us.
0:27:16 > 0:27:21The Ambo Points have been counted and independently verified by me.
0:27:21 > 0:27:24And the winner of the Ambo is...
0:27:32 > 0:27:36Oh, no, wait! It's a draw! Oh, guys, this is so exciting!
0:27:36 > 0:27:38You're both winners! Bring it in.
0:27:38 > 0:27:41Oh, so much love. Let's take a look at both of you in action.
