The 12 finalists on Pop Idol will be hoping for a special Christmas present this year - the Christmas number one.
All 12 of them will team up to record a new version of one of the most famous Christmas single - John Lennon's Happy Xmas (War Is Over).
They're already being tipped for the top spot, ahead of former favourites The Darkness.
Boyband Blue and Sir Cliff Richard are other big names hoping to be number one on Christmas Day.
