Fall Out Boy lead singer Patrick Stump was arrested in Hollywood on Tuesday night.

Stump was busted on a traffic warrant for driving without a license, just after midnight, The Associated Press has learned.

The rocker was taken to the West Hollywood Sheriff’s Station, where he was booked and photographed for a mugshot that exhibits all the stuff that “Caption This” contests are made of. My — what an unfortunate looking hairline. It’s no wonder Pat’s always rockin’ trucker hats!

He was released at 5 AM Wednesday, after posting $15,000 bail.
