Chace Crawford was charged on Friday with a misdemeanor charge of pot possession, TMZ reports. The 24-year-old Gossip Girl star could face up to six months behind bars.

Crawford was busted with a pal in a car parked outside a pub in his hometown of Plano, Texas on June 4; police discovered an unlit marijuana joint.

"He is pissed," an insider told Us Weekly immediately after the arrest. "He wasn't smoking, the pot was in the car and it was his friend's."

Yet an old frat brother of the actor's from Pepperdine University says the star indulged back in the day. "In college, we use to cut class and go lie on the beach and smoke weed," the pal says. "It sucks that he got arrested!"
