R&B singer Cee Lo Green has reportedly been cast to play Wu-Tang Clan member Raekwon's father in an upcoming documentary about the rapper.  The film will be titled "C.R.E.A.M.," and the script is still being finalized, but the former Gnarls Barkley singer has already been given the role.  "[He"s] a good friend of mine," says Raekwon about Green. "When I called him and told him about it he was just overwhelmed. He's just one out of the greats that's gonna be on the project."
