Bobby Brown has been released from jail after serving less than a day of his 55-day jail sentence for a driving under the influence conviction.

A sheriff's spokesman said the 44-year-old R&B singer was released after eight hours and outfitted with an electronic ankle monitor Thursday because of jail overcrowding and good behavior.

A spokeswoman for Brown said he is at home with his family.

Brown pleaded no contest to DUI and driving on a suspended license in February and turned himself in Wednesday. He will be required to serve four years on informal probation and complete an 18-month alcohol treatment program.

The conviction is Brown's second for DUI in less than a year. He avoided jail after pleading no contest to a March 2012 drunken driving case.
