Switched on: Last year's X Factor winner Joe McElderry performed his son Ambition before turning on London's Regent Street Christmas lightsThousands of screaming fans wrapped up warm to see last year's X Factor winner Joe McElderry switch on London's Regent Street Christmas lights last night.
The road was cordoned off for the event, which saw Joe perform his single Ambitions and turn on the Narnia film-themed illuminations.
Helping Joe light up London were stars of the new Narnia movie, Ben Barnes, Will Poulter and Georgie Henley.
Warm welcome: Joe and the crowd wrapped up warm for the ceremony on what was a chilly nightCalled The Chronicles Of Narnia: The Voyage Of The Dawn Treader, it's first film adaptation of the CDS Lewis children's books to be made in 3D.
It's based on the book of the same name and again feaures Tilda Swinton as The White Witch and opens in cinemas on 10 December.
Joe also performed his single Ambitions live on X Factor last month, but saw it chart at a disappointing Number Six.
