Perhaps the strongest indication that Puff Daddy's future will be mostly inside of a prison cell is that his ex Cassie is cooperating with the feds in the sex trafficking case they are building against the disgraced mogul.

She's doing so even after he settled her lawsuit against him for an estimated $30 million.

He hasn't settled Rodney "Lil Rod" Jones's lawsuit against him.

Jones, who produced on Diddy's last album, has accused the Diddler of harassing him, drugging him, and handling his anus.

According to TMZ, Jones is also ready and willing to work with the government to take Puff down.  However, they have yet to contact him.

"Still, our sources say Rodney is willing to cooperate with the authorities if they choose to contact him ... but for the time being, we're told he's being patient and feels somewhat vindicated by the feds obtaining search warrants to raid 2 of Diddy's homes."
