Christina Collab On New T.I. Album, 'No Mercy'

Two days after T.I. reported back to an Arkansas prison to begin an 11-month sentence for probation violation, his album No Mercy finally has an official release date. No Mercy, originally titled King Uncaged will hit the stores December 7 before a recent switch, has seen numerous delays. A tracklist has yet to be revealed, but Atlantic also revealed that Kanye West, Eminem, Chris Brown, The-Dream, and Christina Aguilera will all provide guest vocals.
