Simon Cwowell has admitted that he is considering a Christmas X Factor chart battle.

He knows that the X Factor winner is almost guaranteed a Christmas number one, and the only person he thinks can challenge them is last years X Factor winner, Leona Lewis.

A source told the Daily Star Sunday: “The winner of this year’s X Factor is almost guaranteed the Christmas No.1. But Simon believes the only performer who could upset the apple cart is Leona. For him, it’s a win-win situation because whatever happens he is all but certain of getting the top two spots.”
