Amanda Bynes seemed to have fallen off the wagon again when she was seized in Los Angeles at 3 a.m. on Sunday after police determined she was driving under the influence of a controlled substance.

The former "She's the Man" star reportedly had been driving alone in a 2013 white Mercedes ML350 when she was busted by cops.

A California Highway Patrol officer allegedly saw the 28-year-old blow through a red light and then suddenly stop in the middle of an intersection in Sherman Oaks, Calif.
