Ex-reality star … or career criminal?

MTV reality star Jason Wahler was arrested again Sunday night in Hollywood for allegedly hitting a woman at a party. This marks the seventh time Wahler, 23, has been arrested in recent years, with violations ranging from two DUIs to disorderly conduct to assaulting a tow truck driver.

Wahler, the ex-boyfriend of ‘The Hills’ good girl Lauren Conrad, was taken into custody around 1:45 a.m., booked on a misdemeanor battery charge, and is currently being held on $20,000 bail.

“I am ashamed of everything,” Wahler said to Us Magazine after back-to-back arrests in March for a DUI and a bar fight in Mexico. “I never want to drink again … God did that to me, so maybe I would be at [rock] bottom and want to climb my way to the top.”

They don’t call him the bad boy of ‘The Hills‘ and ‘Laguna Beach‘ for nothing.
