LEONA LEWIS has been paid £1million to perform at a 21st birthday party.
The X Factor winner sang for 200 partygoers at the party for Libby Caudwell, the daughter of Phones4U founder John.
The Run singer was also joined on stage by Boyzone singer Stephen Gately and then dueted with the birthday girl on 'Bleeding Love'.
A source said: "Leona was not supposed to do any live shows until next year, but she made an exception. It's a hell of a lot of money and was a great party, so it was fun being involved."
A guest added: "It was a night Libby will certainly never forget. It was like a dream. She has not stopped talking about it ever since.
"Libby knew something was going to happen, but she just couldn't believe it when Leona walked on the stage."
A spokesperson confirmed that Lewis had performed at a "private event" but said that all details were confidential.
