Former MTV reality star Jason Wahler should head for the hills... and stay there. The 23-year-old is likely looking at some serious jail time, thanks to his latest criminal infraction. The one-time boyfriend of Lauren Conrad was arrested yet again over the weekend -- this time for driving under the influence. It had been a whole week since the Laguna Beach/Hills bad boy had been busted in Cabo San Lucas, Mexico. Wahler was driving his 2008 Chevy Tahoe when he was pulled over, charged with DUI and later released on his own recognizance. Over the last few years, Wahler has been thrown in the clink at least six times. Last week, he made headlines when video of Wahler being handcuffed and escorted to a Mexican jail hit the Internet. Although he was released soon after, the details surrounding his arrest were mysteriously kept very quiet. In 2007 Wahler told People magazine that alcohol is his drug of choice. "I did try drugs, but it was never my thing. It was alcohol, for sure. It would take me about 10 drinks before that other side came out. It's like Dr. Jekyll and Mr. Hyde. I'm embarrassed as hell, but I really do not remember my arrests. They're blackouts. And that's scary." Paging Dr. Drew. Lately, Wahler's career has been at a relative standstill. Might we suggest a spot on Celebrity Rehab... or even Cops.
