Take That and Susan Boyle have both agreed to appear on Simon Cowell's charity record.

The pop singers have joined an ever growing list of stars who will record a version of REM's song 'Everybody Hurts' to aid the victims of the two earthquakes that have struck Haiti in the last two weeks.

Susan told The Sun newspaper: "The Haiti earthquake has caused devastation and suffering that most of us will never experience nor could imagine.

"I feel privileged to be a part of such a wonderful project that will raise money to help the country."

The line up for the single so far includes Rod Stewart, Mika, Michael Buble, Cheryl Cole, Leona Lewis, JLS and Westlife and Alexandra Burke.

'Broken Heels' singer Alexandra is flying from Germany to the UK on Monday to record her part for the song.

She said: "I hope the single raises lots of money. It's great that we can come together and do this. It's a very special song."

REM have agreed that all royalties from the single - including those they would get from originally writing the song - will go to the Haiti appeal.

Lead singer Michael Stipe said: "Any time anyone does something good, or tries to do something positive, the world shifts ever so slightly towards love and towards goodness."

U2 and Jay-Z are also assembling their own charity single to raise money for the disaster in the US.
