Lady Gaga, Eminem, Jay-Z, Justin Timberlake and Barbra Streisand are just a handful of the 100-plus stars scheduled to take part in a re-recording of "We Are the World" to benefit Haiti, producer RedOne told Rolling Stone yesterday at the Grammys. Other artists contributing to the new "We Are the World" — a remake of the 1985 USA for Africa charity single that was co-written by Michael Jackson and Lionel Richie — include Celine Dion, Fergie, Wyclef, Enrique Iglesias and more musicians who attended yesterday's 52nd Annual Grammy Awards.

"I'm so delighted and so happy to get a dream call from Quincy Jones and Randy Phillips and Lionel Richie," RedOne told RS. "I know that Lionel Richie has been asked like 150-something times to redo 'We Are the World' and he said no to everything until this Haiti thing happened. The moment he saw that it happened he was like, OK, 'We Are the World.' And to be one of the people they called to have fresh input to the song, to help produce the song — I have no words."

According to RedOne, recording of the "We Are the World" remake will take place today in a Los Angeles studio. In addition to the all-star vocal talent, RedOne promises instrumentation from the likes of Orianthi (the guitarist for Michael Jackson's This Is It show) and other big-name musicians. The AP reports Bono, Jason Mraz and Akon are also slated to appear on the track. "With music you want to help people feel something in a certain way, and this is something devastating that just happened and I am and we are the world," RedOne said. "We're going to be helping people that we don't know. I have Haitian friends and stuff like that, but we're going to be helping people that need help right now."
