Bobby Brown has been arrested on suspicion of driving under the influence, according to officials in California.
The 43-year-old is the ex-husband of Whitney Houston and is a founding member of the group New Edition.
California Highway Patrol Officer Mike Harris said Brown was arrested north of Los Angeles. He failed a field sobriety test and was arrested on suspicion of driving under the influence.
Harris said an officer initially pulled over the R&B singer after seeing him talking on his mobile phone without a hands-free unit. Harris said the officer observed that Brown appeared to be impaired.
Brown was later released, Los Angeles police said.
