Fall Out Boy vocalist Patrick Stump was arrested in Los Angeles late Tuesday night after being picked up for a two-year-old warrant for driving without a license. Stump was released yesterday after posting $15,000 bail. The warrant is the result of Stump's 2007 failure to appear in court on a misdemeanor charge of driving without a valid license. There is no word on whether this will hamper the band's plans to play Reading Festival in England tomorrow.

Fallout Boy most recently released 2008's Folie á Deux. Stump has also taken up a music review position at Rolling Stone Magazine.
