Jason Wahler Arrested Again

Good news: Jason Wahler was not busted for DUI last night.

Bad news: He was busted for assault. 

Law enforcement sources tell TMZ they were called to a party in Hollywood early this morning after a girl, not Wahler's girlfriend, complained the former "Hills" star struck her after an argument.

Wahler was arrested and booked for misdemeanor battery.
