When it comes to a duet for Mariah Carey and Janet Jackson, Jermaine Dupri does mean it. The record producer and rapper takes the project seriously as he's now developing an idea for the two divas to duet on a new song.

"It's gonna happen on this record," Dupri hinted on the possibility for Mariah and Janet collaboration. "Please believe that. I got a mean idea, so look for it. We definitely gonna do a repackage on [Janet's "20 Years Old"] once it comes out. Hopefully it's successful and people buy into it, then I'm going back in the studio," he added.

However, JD said that if he can get the song done in time, it could even wind up on the initial pressing of Janet's album rather than a re-issue. "It depends on how quick my mind moves," he said. "We're mixing records for ["20 Years Old"]. We're not done yet. I'm thinking I might go back in, and I might tamper with it... We gotta try to figure it out."

Dupri hopes to have the duet mapped out and recorded before Carey embarks on her summer tour. In fact, he will probably even show up at some of her dates.
