LOS ANGELES (Reuters) - Singer Bobby Brown, the ex-husband of the late Whitney Houston, was sentenced to 55 days in jail on Tuesday after admitting to driving drunk last year. Brown pleaded no contest, an admission of guilt under California law, to driving under the influence and driving on a suspended license in October in a Los Angeles suburb.

Brown did not appear in court on Tuesday and his plea was entered by his attorney. ...
