Robbie Williams, Take That and Kylie Minogue join the growing list of music stars lending their vocals to Simon Cowell's charity single for Haiti.

Williams is set to reunite with Take That to record their lines from R.E.M's 1993 anthem 'Everybody Hurts' together in Los Angeles.

He told The Sun: "I'm very honoured to be asked to contribute to the single.

"We can all do something to help the people of Haiti and I urge everyone to do what they can."

Leona Lewis, JLS, Alexandra Burke, James Blunt and Joe McElderry have already recorded their vocals, while Mariah Carey and Miley Cyrus will be doing theirs this week.

Up to 200,000 people are feared dead in Haiti following the 7.0 Richter scale earthquake on January 12th.
