HUNTINGTON BEACH, Calif. (AP) _ Backstreet Boys singer Nick Carter was charged Tuesday with drunken driving, prosecutors said.

Carter, 25, faces one count of driving under the influence and one count of driving with a blood alcohol level above 0.08, said Assistant District Attorney Ted Burnett.

Carter was scheduled to appear for an April 13 arraignment, but could send his attorney instead because the charges are misdemeanors, Burnett said. He could face fines of nearly $1,500, license restrictions and informal probation, if convicted.

Carter was behind the wheel of a vehicle observed committing an unspecified traffic violation when police officers stopped him Saturday about 7:30 p.m. downtown, police said.

``Nick Carter deeply regrets the current situation. He is on doctor prescribed medication and was unaware of its interaction possibilities,'' Carter publicist Juliette Harris said Monday in a statement. There was no elaboration on the prescriptions.

The Backstreet Boys, whose hits included ``I Want It That Way,'' ``Shape of My Heart'' and ``Show Me the Meaning of Being Lonely,'' recently announced they were embarking on a 13-city concert tour starting March 21 in New York.

In 2002, Carter released a solo album.
