The stars in Bono and Jermaine Dupri's all-star remake of Marvin Gaye's "What's Going On" are multiplying.

Staind singer Aaron Lewis, P. Diddy and Nelly Furtado are among the musicians who have joined 'NSYNC, Britney Spears, Destiny's Child, Alicia Keys and others in recording the benefit single, which will be released on World AIDS Day December 1, Dupri's spokesperson said Monday (September 10).

Lewis was in New York's Battery Studios on Wednesday, along with rapper Nelly, Gaye's daughter Nona Gaye and previously reported performers Wyclef Jean, Christina Aguilera and No Doubt frontwoman Gwen Stefani.

The Roots' ?uestlove laid down drum tracks on Wednesday, and Bono recorded the first of two days' worth of vocals. Dupri is producing the "We Are the World"-like song, which will raise money for AIDS research.

On Friday, after a day off for the MTV Video Music Awards (see [article id="1448724"]"Britney, J. Lo, 'NSYNC Turn To Jungle, Ja Rule, Jacko For VMA Performances"[/article]), Furtado, Backstreet Boys, Lil' Kim, Mary J. Blige, Eve, Nas, U2 bassist Adam Clayton, R.E.M. frontman Michael Stipe and Savage Garden singer Darren Hayes joined Dupri in the studio.

P. Diddy put his Bad Boy touch on the song on Saturday, Dupri's publicist said.

Marc Anthony and Maxwell will contribute by recording vocals elsewhere and sending them to Dupri, who will also host last-minute recording sessions for the single this week with Fred Durst, Jennifer Lopez and Jagged Edge.

Bono is organizing the project, which he is calling Artists Against AIDS Worldwide (see [article id="1448662"]"Britney, 'NSYNC, All-Star Lineup To Record Marvin Gaye Classic"[/article]).

The Global AIDS Alliance originally asked Bono and Wyclef Jean to record the song; however, Bono had other ideas.

"I just thought, you know, we're the usual suspects. Don't come to us. We're too right on," Bono said backstage at the VMAs. "Go raid the pop charts. Go ask Britney Spears. Go ask Jennifer Lopez. Go ask 'NSYNC. Go ask the rappers,

the hip-hop guys like Ja Rule or Nelly or DMX. In fact, [they] made me go ask them and I did. They all agreed and we've got like 25, 30 of the most extraordinary people on this record now.

"I'm very proud of it," he added. "I think the record is going to work out great. I think it's going to be a big hit single this Christmas."
