Sometime in the next few weeks, Bobby Brown will have to begin serving time behind bars.

TMZ.com reports Whitney Houston's ex was sentenced Tuesday to 55 days in jail after pleading no contest to DUI and driving on a suspended license in connection with an arrest last October in Los Angeles.

Bobby, who has three DUI convictions under his belt, must turn himself in by March 20.  He must also serve four years' probation. The singer had already been on probation before his latest arrest, but a judge subsequently revoked it.
