Jason Wahler Arrested For Sixth Time

The Hills's Jason Wahler is facing almost certain jail time following a drunk driving arrest in Newport Beach, Calif., Friday evening.

Wahler, 23, was taken into custody at 10:54 p.m. for DUI while driving a 2008 Chevy Tahoe, Newport Beach Sgt. Evan Sailor confirms to PEOPLE. He was released on his own recognizance hours later.

Last week, video surfaced online of Wahler being cuffed by Mexican police in Cabo San Lucas March 11 after he allegedly got into a fight at a nightclub.

This is at least the sixth drinking-related arrest for Wahler in recent years.

In a 2007 interview with PEOPLE, Wahler admits: "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."

Last year, Wahler, who once dated Lauren Conrad, saw his engagement to college tennis player Katja Decker-Sadowski called off.
