T.I. and Puff in a photo dated February 9, 2009

Rapper T.I., who is serving the final month of his prison sentence on house arrest after leaving a halfway house, has been grinding in the studio putting the finishing touches on his album. My sources tell me that music producer and sometime rapper, Sean Combs, was in the studio with T.I. yesterday working on a few tracks.

Music producer Lil C, left, is producing most of T.I.’s tracks on his as yet untitled album. The producer joined Atlanta’s hottest female promoter, Tracy Bryant (Kind Of A Big Deal), and rapper Nelly at Club Obsessions last night.

According to an inside source, Nelly was the only rap artist who took his tour bus to Arkansas to visit T.I. while he was in prison. No other artist took the time to visit T.I. He gets much respect for that.
