Kelly Price has agreed to join Foxy Brown, Busta Rhymes, and Deborah Cox on R. Kelly's upcoming tour, and Nas may not be far behind.

Nas is currently negotiating a slot on the tour, which kicks off on May 5 (see "R. Kelly, Foxy Brown, Busta Rhymes, Deborah Cox To Team Up For Tour"). The timing would be perfect for the New York rapper, who has his third album, "I Am," arriving at the end of this month, and a new DJ Premiere-produced single, "Nas Is Like," arriving now.

There's no word yet on what this R. Kelly-headlined production might look like, but we'll keep you posted.
