Celine Dion, Lil Wayne, Nick Jonas, Janet Jackson and dozens of other music stars gathered to record the 25th anniversary version of "We Are the World" in Hollywood on Monday, and ABC News cameras were there to capture the historic moment. The recording was organized by Quincy Jones and Lionel Richie, who co-wrote the original "We Are the World" with Michael Jackson.

'We Are The World': Behind The Scenes

As Billboard reported yesterday, Janet Jackson tackled her brother Michael's solo from the original "We Are the World," while Lil Wayne sang the part performed by Bob Dylan. "Did I do a better job than Bob Dylan? Hell, no," Wayne said after the recording.

At 83 years old, Tony Bennett is the elder statesmen of the new "We Are the World" lineup, while 15-year-old Justin Bieber clocks in as the youngest.

"We Are the World - 25 for Haiti" will premiere in 3D on Feb. 12, during the opening ceremony of the Vancouver Winter Olympics on NBC.
