Music mogul Simon Cowell has chosen an upbeat Hannah Montana ballad for the Christmas X Factor song.
Miley's track, The Climb, will be recorded by each of the three X Factor finalists in preparation for its release as soon as the winner is announced in two weeks' time.
Despite the success of his own two acts, Danyl and Olly, Simon has revealed he thinks Cheryl's remaining act will win the show.
"I think Joe will win. More women and girls will vote for him than anyone else," he says.
Olly Murs - tipped as favourite - is showing he is fully committed to the show.
The 25-year-old is missing his brother's wedding - for which he was best man - on Saturday.
