[artist id="2490602"]Leona Lewis[/artist], [artist id="16935"]Rod Stewart[/artist] and [artist id="1233884"]Michael Bublé[/artist] have all signed on for Simon Cowell's charity single to benefit Haiti. The "American Idol" judge announced he'd be putting together a lineup for the song on Wednesday in London.

Boy band JLS, who competed on Cowell's "The X Factor" in 2008, will also be involved, the BBC reports. They will be covering R.E.M.'s classic song "Everybody Hurts." The Sun newspaper, which is working with Cowell on the project, reports that Cowell is trying to get Robbie Williams, Coldplay, Take That and Paul McCartney on the track as well.

"The agony and anguish for the people that we are seeing on our television screens is something that British people want to respond to," said Prime Minister Gordon Brown, who reportedly asked Cowell to organize a charity single. "Simon Cowell can make a huge amount of money to help the people of Haiti."

The BBC also reports that a number of acts including Coldplay, Blur's Damon Albarn, the Arctic Monkeys, the Chemical Brothers, the Kooks, the Pet Shop Boys, Klaxons and Pearl Jam are participating in an eBay auction that was set up by Glastonbury Festival organizer Emily Eavis. Albarn recorded a song for the auction and Coldplay's Chris Martin signed a Viva La Vida tour jacket.

The auction, which started Friday (January 22), will run for 10 days. "I visited Haiti with Oxfam a few years ago. It's a country of extreme poverty and brutal living conditions. Most people in Port-au-Prince live in tin shacks," Martin said. "The earthquake that has struck Haiti will have turned the city into an unimaginable hell."
