Simon Cowell is to make a charity single to raise money for quake-hit Haiti.
The X Factor judge said the urgent fundraising effort - which could involve stars such as Susan Boyle and Leona Lewis - followed a request from the Prime Minister.
It could also see VAT waived on all sales of the track to maximise money raised.
Speaking at the National Television Awards ceremony in London, Cowell said: "We made the decision today.
"We had a request from the Prime Minister and The Sun newspaper, 'Would we put a record together?', so we haven't got a lot of time but we are going to do something, and attempt to raise as much money as possible."
He also said that fellow judge Cheryl Cole "would love" to be part of the single.
