Katt Williams: My Greedy Family Wants Me In The Loony Bin

Katt Williams' downward spiral has scared his loved ones so much they want him hospitalized ... but the comedian thinks it's just a ploy to get his cash.

Katt tells us his "so-called family" has turned up the heat on him to get professional help, after a video surfaced that showed him getting into it with a 17-year-old. Katt grouses his family's been trying to get him hospitalized for years ... but only because they're a bunch of "broke bitches."

Katt's suspicions have grown to the point he fired his entire team ... a team he says has been fleecing him.

The family begs to differ, claiming Katt needs help. A source close to Katt tells us the comedian is so off the rails, he was found naked and covered in chocolate when cops raided his house earlier this month.
