The X Factor finalists are to release a cover of Michael Jackson's You Are Not Alone to raise money for sick children, it has been announced.

All 12 acts in the ITV talent show recorded the charity single, which will be sold in aid of London's Great Ormond Street Hospital.

Viewers will see the singers perform the track for the first time during the results show on Sunday November 15, when fans will be able to pre-order it.

The single will go on sale from Monday November 16.

Jackson, who died in June, went to number one with the song in 1995.

Last year's first X Factor charity single - a cover of Mariah Carey's Hero - raised more than £1m for the Help For Heroes charity.

Simon Cowell said: "Following last year's record we made with the X Factor finalists in aid of Help For Heroes last year we decided we wanted to do something annually on the show to help good causes.

"This year we chose to work with Great Ormond Street to help raise funds and awareness for their incredible work. I'm very proud of the single and I really hope it raises an enormous amount of money for people who really need our help."
