Bobby Brown is officially locked up.
The singer turned himself in moments ago in Los Angeles to begin his 55-day jail sentence following his most recent DUI conviction (his third career).
Brown also got four years probation stemming from the October 2012 arrest, and he will have to complete an 18-month alcohol program as a result.
Because of jail overcrowding, as well as time off for good behavior and credit for "good time work time," Brown is likely to serve no more than nine days.
Hopefully this DUI is his last.
