:00:08. > :00:11.stories this Sunday. The talking robots making history in
:00:11. > :00:21.space. And they're small, blue and coming
:00:21. > :00:23.
:00:23. > :00:29.to a screen near you! The Smurfs are First to a massive showbiz secret so
:00:29. > :00:33.secretive that it's even been given a code name! But in a matter of
:00:33. > :00:37.hours, we will all know who the new Doctor Who will be. The 12th Doctor
:00:37. > :00:39.will be revealed in a one-off live programme on BBC One at 7pm which
:00:39. > :00:43.will also feature a special interview with Matt Smith, who
:00:43. > :00:48.announced he would be stepping down in June. CBBC's Chris, who's a
:00:48. > :00:54.superfan, told me why it's going to be so exciting.
:00:54. > :00:58.It is exciting to find out something we have wanted to know for a while,
:00:58. > :01:02.since Matt Smith announced he was leaving. They are not just telling
:01:02. > :01:12.us. They are doing a big announcement. It is like Christmas!
:01:12. > :01:12.
:01:12. > :01:16.This is a first. He was announced in a special press release. But tonight
:01:16. > :01:20.is like a concert, bringing out the final act. It means we will all find
:01:20. > :01:23.out at the exact same moment. No-one will know beforehand, apart from
:01:23. > :01:27.those who already do. We will all be there at the same time.
:01:27. > :01:30.Well, on the website we've been asking you, what would be the first
:01:30. > :01:40.thing you did if you became the new Doctor? And we've had some great
:01:40. > :01:52.
:01:52. > :01:56.More than 20,000 cyclists are expected to take part in a 100-mile
:01:56. > :01:59.race around London today. The riders started their journey at the Olympic
:01:59. > :02:03.Park. And thousands have already crossed the finishing line. As well
:02:03. > :02:10.as pro riders, lots of cyclists have been taking part to raise money for
:02:10. > :02:13.charity. It's all part of RideLondon, a huge cycling event
:02:13. > :02:19.this weekend. Former Olympic rower James Cracknell was the first celeb
:02:19. > :02:25.cyclist to finish the race. Having cycled around London and box Hill, I
:02:25. > :02:29.grew up around this area, with cars normally, it is brilliant to have
:02:29. > :02:33.total run of the road. The best thing was being in the Olympic
:02:33. > :02:40.Park, where I was last year, and so many people were flooding like they
:02:40. > :02:42.one year ago, but they are actually doing something rather than just
:02:42. > :02:45.clapping. And Double Olympic gold medallist
:02:45. > :02:48.Laura Trott sprinted to victory in the first ever RideLondon Women's
:02:48. > :02:52.Grand Prix yesterday. She finished one bike length in front of her
:02:52. > :02:57.rival in the 15-lap criterium event around the streets of the capital.
:02:57. > :03:02.And the key to her success - a sneaky sandwich.
:03:02. > :03:05.Jam sandwiches! I love them. I always make sure I make them in the
:03:05. > :03:10.morning so they are ready, and then I have them in my back pocket to
:03:10. > :03:13.pull out. Next to sport. He's been in the
:03:13. > :03:16.middle of a transfer tug-of-war all summer. And the latest twist in the
:03:16. > :03:19.battle for Gareth Bale is that his boss, Andre Villas-Boas, has
:03:19. > :03:21.criticised Real Madrid for going public with their interest in
:03:21. > :03:25.signing the Wales international player. According to the Tottenham
:03:25. > :03:27.manager, Bale, who scored 26 goals for Spurs last year, is not for
:03:27. > :03:29.sale. Now, she's had countless number
:03:29. > :03:34.ones, two best-selling albums and sold-out live shows across the
:03:34. > :03:37.world, but did you know Katy Perry is also a bit of an actress? She's
:03:37. > :03:40.the star voice on the new Smurfs movie, which sees her character
:03:40. > :03:48.Smurfette kidnapped by Gargamel, who is even eviler than last time.
:03:48. > :03:55.Here's Nel. They are the little blue people used
:03:55. > :03:59.to getting into big trouble. Smurfs two sees the return of an all-star
:03:59. > :04:03.Kast, including Katy Perry in the lead role of Smurfette. The sequel
:04:03. > :04:08.is about her story, because she was created by Gargamel, the villain,
:04:08. > :04:14.and she found goodness. No matter what situation you are born in, you
:04:14. > :04:22.can always grow. The Smurfs set off to rescue her after she is kidnapped
:04:22. > :04:28.by Gargamel. But they are up against it with Gargamel even more fiendish
:04:28. > :04:33.than before. The phone with a character like this is that he is so
:04:33. > :04:37.evil, it is ridiculous. There is nothing subtle about him. Katy Perry
:04:37. > :04:41.got the part after the film-makers picked her voice out of hundreds of
:04:41. > :04:46.others. They had heard a snippet of my voice from an interview, and it
:04:46. > :04:53.must have been a morning radio interview, because of Smurfette has
:04:53. > :04:58.got more gravel to her voice that I typically have. Don't worry, music
:04:58. > :05:03.fans, because Katy Perry is still working on herself album -- on her
:05:03. > :05:10.third album. It is a lot of effort to be an actress and is not just
:05:10. > :05:20.something I roll into. It does not always work. You really have to work
:05:20. > :05:26.
:05:26. > :05:29.Next, the Duke of Cambridge has made his first public appearance since
:05:29. > :05:34.the birth of his son, Prince George, just under two weeks ago. Prince
:05:34. > :05:37.William took a breather from being a new dad to play in a charity polo
:05:37. > :05:39.match. After the game he was presented with a child's polo
:05:39. > :05:42.mallet. Maybe a bit big for Prince George.
:05:42. > :05:46.And finally, a talking robot is on its way to the international space
:05:46. > :05:49.station for the first time. Kirobo will provide company for a Japanese
:05:49. > :05:53.astronaut who is due to arrive at the station later this year. When
