Susan Boyle has signed on to sing REM's "Everybody Hurts," along with a long list of other stars, to benefit the victims of the earthquake in Haiti.
Simon Cowell will produce the tune, and Rod Stewart, Michael Buble, Leona Lewis and JLS have already signed on to lend their vocals, according to People.
"I don't know who's available, but I will get a record out within seven to 10 days," Cowell said on Thursday. By Friday, he had those stars lined up and reportedly had approached Paul Mccartney, Coldplay and Robbie Williams, according to the BBC.
Cowell, who recently announced he will leave "American Idol" after the current season to launch a new show, said he was asked to help the cause by British Prime Minister Gordon Brown.
The 7.0 magnitude earthquake that struck Port-au-Prince on Jan. 12 killed as many as 200,000 and left millions homeless. Cowell is just the latest star to get involved in the ongoing relief effort. A telethon hosted by George Clooney airs Friday on all major networks, and will feature performances by Bruce Springsteen, Jay-Z, Taylor Swift, Justin Timberlake, Keith Urban and Alicia Keys.
Clooney has personally donated $1 million, as have Sandra Bullock, Brad Pitt and Angelina Jolie and Microsoft founder Bill Gates. Supermodel Gisele Bundchen gave $1.5 million.
