Robbie Williams is going head-to-head with the X Factor winner in the race for the Christmas number one.

The former Take That star is releasing the second single from 'Reality Killed The Video Star', 'You Know Me', on Monday December 14 just in time for the coveted chart race.

Robbie, who was beaten to number one by Alexandra Burke the other week, will have his work cut out – the last four Christmas number ones in the UK have been X Factor winners.

This year's X Factor song is already the bookies' favourite.
