X Factor winner Leona Lewis is reportedly about to fly out to the US to sign a £5 million contract across the pond.

The 21-year-old will jet out next Thursday to meet music exec Clive Davis, the man behind Whitney Houston, Dido and Angie Stone, reports the Daily Mirror.

She will be joined by Simon Cowell, her mentor on the show.

“Leona’s X Factor prize is peanuts compared to what Clive is offering,” an insider told the paper.

“When Clive called Simon Cowell, he was talking £5 million. Leona and Simon will fly to meet him.”

A staggering 12.6million viewers tuned in to watch Leona take the X Factor crown on Saturday night and now bookies have closed their betting on the Christmas No 1, as they fear no one will beat her.

Leona’s single, A Moment Like This, is already estimated to have sold 200,000 downloads. It will be in the shops on Wednesday.

The single is a cover of the No 1 song which Kelly Clarkson released after winning American Idol in 2002.
