Peter Capaldi will be the next Doctor Who - it's official!
The BBC unveiled the 12th Time Lord in a live show on Sunday evening.
The secret's out... Peter Capaldi is the new Doctor Who
"It's so wonderful not to keep this secret any longer," he said after he walked out on stage. "For a while, I couldn't tell my daughter, who kept looking on the internet, and was getting upset because they never mentioned me.
"I had to keep saying, 'Rise above it, darling.'"

He will replace Matt Smith at the end of the year, during the show's Christmas special.
Capaldi revealed he was a lifelong fan of the sci-fi favourite, although he revealed, "I haven't played the doctor since I was nine in the playground."
The identity of the new Doctor was successfully hidden up until the last minute, with even the show's presenter Zoe Ball only being told the name just before the beginning of the live show.
Ben Stephenson, Controller of BBC Drama Commissioning, explained, "Amongst all the speculation and betting, there has been lots of fun and intrigue at work as we've been using the codename Houdini as a decoy!
"It's the biggest secret in showbiz, even those working with the new Doctor on other projects at the moment have no idea they are in the presence of the 12th incarnation."
Show writer Steven Moffat had announced in a statement previously, "The decision is made and the time has come to reveal who's taking over the TARDIS. For the last of the Time Lords, the clock is striking twelve."

Guests on the show, hosted by Zoe Ball, included the 5th Time Lord, Peter Davidson and the current incumbent, Matt Smith.
Matt Smith told the audience, "I've loved it and I'm really going to miss it. But, when you've got to go, you've got to go."
Speaking in high praise of Peter Capaldi's casting, Matt Smith said, "It had to be him."
The new Doctor Who is a Patron of the Association for International Cancer Research, and of a Scottish children's charity, the Aberlour Child Care Trust.
Peter Capaldi is 55. That's 25 years older than Matt Smith, the 11th Time Lord, and the same age as the very first Doctor Who William Hartnell.
As well as all his BAFTA award and two British Comedy Awards for his portrayal of Malcolm Tucker in 'The Thick of It, Capaldi has an Live Action Short Film Oscar on his shelf - for his 1995 film celebrating the work of German author Franz Kafka.
Capaldi lives in North London with his wife Elaine and daughter, from whom whom he had to keep it secret that he was to be the next Doctor Who. "She was looking at the internet, and getting upset when there was no mention of me," he revealed. "I had to say, 'Rise above it, darling.'"
In a 30-year career, Capaldi has appeared on small and big screen, as well as the stage. His face will be familiar from all sorts of things, from 'The Vicar of Dibley', to 'Prime Suspect 3', 'Skins', 'Midsomer Murders', 'Psychos', 'Peep Show', 'Waking the Dead'. even a 2008 episode of 'Doctor Who: The Fires of Pompeii'. He will be co-starring with Benedict Cumberbatch in the forthcoming film about Wikileaks, 'The Fifth Estate'.

He got his big break in the 1983 film 'Local Hero', where he played Oldsen, distracted from plans of empire-building by the sight of Jenny Seagrove swimming.
Peter Capaldi recently appeared in Brad Pitt's apocalyptic blockbuster 'World War Z'. Spookily, Capaldi played 'W.H.O doctor' - just a suitable World Health Organisation acronym, or did they know something we didn't?!
Until now, Peter Capaldi's most celebrated role is that of government spin doctor Malcolm Tucker, a man who can turn the Cabinet Room blue with his stream of personal invective. Example: "When I want your opinion, I'll give you the signal, and the signal will be me being sectioned."
