After more than a year of apparently being held up by his old label, Jive Records, OUtkast's Big Boi has signed a new deal with Def Jam and is rumored to be on the verge of finally releasing his new album, "Sir Lucious Leftfoot: The Son of Chico Dusty". The album is reportedly loaded with big-name celebrity guests, including Mary J. Blige, Andre 3000, Raekwon, T.I., Lil Jon, Jamie Foxx and B.O.B.
