Justin Bieber, Miley Cyrus And Jonas Brothers Mingle With Music Legends For 'We Are The World' Remake

Oh, to be a fly on the wall at Henson Studios during yesterday's marathon "We Are the World" recording session. It seems like everyone who's anyone in the music industry spent hours yesterday recording a new version of the famous charity single from the 1980s, with proceeds to benefit the Hatian earthquake relief effort. Hollywood Crush favorites like the Jonas Brothers and Jennifer Hudson sang alongside legends like Harry Connick, Jr. and Carlos Santana. Even new pop stars like Miley Cyrus sang with pop vets like Pink, who was fresh from her acrobatic performance at the Grammys on Sunday night.

After the jump, see what other famous faces MTV spotted at the "We Are the World" recording!

Justin Bieber wasn't just at the studio to lend his support in the chorus: according to the MTV News report of the event, Justin has a major part in the piece — he sings Lionel Richie's original opening line! As you can tell from the photo below, featuring Celine Dion, Will.i.am, and Barbra Streisand chatting with the teen (who ever thought you'd see that group in a conversation together!??), the star-studded performance drew all types of celebrities. According to a press release from the organizers, the resulting song will be available for purchase soon, and the video will debut next Friday during the Vancouver Winter Olympics opening ceremony coverage on NBC.
