Chris Brown got booted out of anger management rehab after only two weeks for—surprise, surprise—getting violently angry.

Earlier this month Brown's mom showed up for a family session and encouraged her son to extend his treatment. A probation report obtained by TMZ says Brown disagreed, violently. He tossed a rock through his mom's car window, shattering it.

It was only Brown's 13th day of treatment at a rehab center in Malibu, and he was booted out because of his outburst. After he was booted out, a judge ordered Brown to 90 days in the facility and drug testing.

The probation report says without therapy and strong support, his prognosis is "very guarded."
