Bobby Brown has been sentenced to 55 days in jail and four years of summary probation for his most recent drunk driving arrest, a spokesman for the Los Angeles City Attorney's Office said.

He was also ordered Monday to attend three Alcoholics Anonymous classes a week and complete an 18-month alcohol treatment program.

Brown's arrest Oct. 24 marked his second in a year. His first DUI arrest was in March 2012.

The 44-year-old R&B singer was sentenced to a 10-day sentence for drunk driving, another 10 days for driving on a suspended license and 35 days for violating his probation on his prior DUI.

Brown must report to jail by March 20.

A representative for Brown told ABC News a mutually acceptable plea agreement was entered into on behalf of Brown and the City Attorney's Office.

"Mr. Brown has accepted responsibility for what occurred last October. Mr. Brown continues to remain committed to his sobriety. Mr. Brown is pleased that the matter has been resolved," Said Christopher Brown, the singer's attorney, said in a statement to ABC News.

He has long struggled with alcohol and drug abuse. He was also charged with a DUI in Florida in 1996.

Brown wed girlfriend Alicia Etheridge in Honolulu last June. Prior to their engagement in May 2010, Brown and Etheridge dated for three years following Brown's split with Whitney Houston in 2007. The couple has one child, Cassius, born in 2009.
