Profits from this year's 'X Factor' winner's single will go to a children's charity.
Simon Cowell has revealed 100 per cent of Syco's profits from CD sales and downloads of the song - which will be performed by the two finalists at the culmination of this year's competition in Manchester on December 9 - will go to Together for Short Lives, which supports those who help, love and care for children and young people who are unlikely to reach adulthood.
The music mogul - who has worked closely with the aid organisation for several years - said: "Together for Short Lives is such an inspiring and important charity for so many kids and their families who really need help and support.
"These hospices are really happy and positive places and are a complete lifeline for so many families. Having worked with this charity for many years I have been able to see first hand how they have impacted so many lives, and I'm delighted that The X Factor's winner single sales will go directly to helping them."
At least £1 for each CD and 20p for each download of the song - which will be available to download once 'The X Factor' winner is crowned at the final on December 9 - is expected to be donated to Together for Short Lives.
The single will be the fifth charity release to come from 'The X Factor', but the four previous efforts - which include last year's cover of the Rose Royce classic 'Wishing On A Star' - have all been group songs performed by a number of contestants.
Barbara Gelb, CEO of Together for Short Lives, added: "We are so delighted to benefit from 'The X Factor' charity single this year.
"Together for Short Lives is the leading UK charity that speaks for all children with life-threatening and life-limiting conditions and all those who support, love and care for them.
"Our work helps to ensure that children can get the best possible care, when and where they need it. We work with the specialist services that care for these children and families, including children's hospices, and every single bought will make a huge difference.
"These services are a real lifeline and your money will help to support families with the challenges of daily life so children and families make the most of precious time together."
Jahmene Douglas, Christopher Maloney, James Arthur and Union J will compete in the 'X Factor' semi-final on Saturday (01.12.12).
