In an effort to raise money for Haitian earthquake relief, a gang of singers, rappers, producers, musicians and other celebrities showed up at Jim Henson Studios yesterday (Mon. Feb 1) in Hollywood to record “We Are the World 25 Years for Haiti,” a remake of Michael Jackson‘s famous “We Are the World” song, which raised at least $30 million for African humanitarian programs 25 years ago.

Quincy Jones and Lionel Richie came together and rounded up folks like Kanye West, Lil Wayne, Jennifer Hudson, Wyclef Jean, Jamie Foxx, Justin Bieber, LL Cool J, Usher, Keri Hilson, Brandy and a ton of other celebrities to lay down vocals and instrumentals for the charity single.

The song and accompanying music video will premiere on NBC next Friday (Feb. 12th) during the opening ceremony of the Winter Olympics. Check out 30+ pictures of celebrities banding together for a good cause below…
