Omarion Locked up for a No-Show

Omarion has been arrested -- for being a no-show.

According to TMZ, the former B2K member was pulled over for running a stop sign early this morning (Friday) in California's San Fernando Valley. When cops ran his license, they found a warrant for his arrest because he'd failed to appear in court for a prior traffic ticket.

Omarion was handcuffed and taken in by the boys. He's being held on $20,000 bail.
