It's back to the studio for Timbaland - and once again, he's inviting along some friends.

For the sequel to his 2007 hit album Shock Value, the musician-producer, 37, is bringing in heavy-hitting collaborators from across the music world, including Beyonce, Rihanna and the Jonas Brothers.

"Right now, I have a song with Madonna that I didn't put on her album. I saved [it] in case I wanna do one for me," he told MTV News.

"Of course I'mma do one with Beyonce. Of course I'mma do one with Jordin Sparks, Rihanna. It's a lot of people. I'mma do one with Jonas Brothers. I'mma try to have 10 major ones."

He'll also incorporate rappers into his lineup, he says. T. Pain has signed on, while T.I. and Jay-Z may also make appearances.

"Jay was really on the last one, but he wanted to change [the song]," he said. "I said, 'Look, man, I gotta put out an album. You're killing me.' "
