T.I. has already collaborated with Big K.R.I.T. and Pharrell Williams in anticipation of his upcoming album Trouble Man, but he's got a trick up his sleeve for the project. Speaking with VIBE.com, producer Caviar revealed that Tip has an unreleased verse from Pimp C in his possession that he plans to include on the pending LP.

“I have a song on T.I.'s new album featuring Pimp C, which is one of his last verses that he did before he passed away," said Caviar. "So Tip was sitting on it, but he got caught up and went to jail. But he told me 'Yo Cavie, keep that sh*t on ice and we rolling with it. Like when I get out it's gonna be on the album.'"

The King of the South recently released his new single "Pyro." For Trouble Man, he has also worked with production duo Two Band Geeks – consisting of Stroud and B. Kang – as well as hit-maker Dr. Luke.
