Bobby Brown was arrested by law enforcement officers at 12:20 PM PST Monday in Reseda, CA for suspicion of driving under the influence.
The R&B singer was originally stopped by officers for talking on his cell phone while driving, but was subsequently given a field sobriety test and taken into custody.
The 43-year-old ex-husband of the late Whitney Houston is currently in custody at the Van Nuys jail. It is not yet known what substance cops suspect Brown had been using.
Brown already has one DUI conviction on his record from a 1996 arrest in Georgia, for which he spent eight days in jail.
