You Are Not Alone is out on 15 November
Proceeds from You Are Not Alone will go to Great Ormond Street Hospital.
The finalists will perform the track live for the first time during the results show on 15 November and it will available to download immediately after.
Last year, a cover of Mariah Carey‘s Hero raised over £1million for Help For Heroes.
‘Following that, we decided we wanted to do something annually on the show to help good causes,’ says Simon Cowell, 50.
‘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.’
