Chris Brown has entered rehab for anger management. Could it have to do with the fact that he faces as much as four years in prison for violating his probation by allegedly punching a guy in Washington, D.C.?

No, Brown wouldn’t do that to curry favor with a judge. He must really feel bad about his behavior and want to change.

By the way, the rehab facility is in Malibu. TMZ says his lawyer dropped him off there after meeting with Los Angeles probation officials, who will decide whether or not the brawl in Washington — which landed him in jail — affects his probation in the Rihanna beating case. We’re guessing yes — though with millionaires, anything can happen.
