Chris Brown has been jailed for violating a judge’s order during his stint in rehab.

According to TMZ, Brown, who has been living in rehab for nearly four months, was told he must stay at the facility whilst his assault case ran its course.

TMZ states, “The judge in the Rihanna beating case ordered Chris to live in the Malibu rehab facility for 90 days to get anger management therapy, and he completed the stint earlier this month. BUT … at the last court hearing, the judge modified things and ordered Chris to stay in the facility while the Washington D.C. assault case ran its course. The deal was this … if Chris left rehab, he would go directly to jail.

Sources familiar with the situation tell TMZ … Brown was thrown out of the rehab facility this morning, for violating “internal rules.” We do not know precisely what Chris did, but we’re told it did not involve violence or drugs.

Chris was picked up by L.A. County Sheriff’s deputies a short time ago and is on his way to jail.”
