Jason Wahler: "I Am Ashamed of Everything"

Former Hills star Jason Wahler says he felt incredible "shame" when he made headlines again last weekend for his sixth alcohol-related arrest in recent years. A week prior, online video footage also surfaced of Wahler, 23, being cuffed by Mexican police in Cabo San Lucas March 11 after he allegedly got into a club brawl.

"I am very ashamed of everything," he tells UsMagazine.com. "I am very sorry for everything that's happened."

So what went wrong for Wahler, who claimed in 2007 that he had cleaned up his act and even did a stint in rehab?

About six months ago, he tells Us he moved back to Orange County from L.A. and enrolled in the University of Phoenix in Fountain Valley, Calif., hoping to earn a business degree. He even began going to AA up to five times a week. "I had a sponsor and stuff," says Wahler. "You know, the whole thing."

While traveling to L.A. "doing the whole movie stuff," he says he "got distracted" and "started falling out of the program ... I lost contact with my sponsor."

On March 19, he was taken into custody at 10:54 p.m. for DUI while driving a 2008 Chevy Tahoe. He likely will face jail time. He declined to talk about the incident, but he tells Us, "I think everything happens for a reason. God did that to me, so maybe I would be at [rock] bottom and want to climb my way to the top."

"It's all about getting back on track," Wahler tells Us. "My girlfriend, my parents, my brothers, my sisters and a handful of my best friends are willing to do everything to keep me out of trouble."

The Hills Family Tree

Lauren Conrad is the center of this tree because everyone is connected to her. Sure she's not on the show anymore, but all these people have dated, worked with, been friends with, lived with, etc. She is the show's matriarch.

Lauren went to high school with and starred on "Laguna Beach" with Kristin Cavallari and Lo Bosworth, she also dated/starred on "Laguna Beach" with Jason Wahler, who made an appearance on "The Hills." Kristin, who joined the "Hills" in its fifth season, had previously dated Brody Jenner, who also dated Lauren. Brody most recently had eyes for former playmate Jayde Nicole.

Kristin also dated Justin Bobby who dated Audrina Patridge, which brings us to Heidi Montag because both ladies have lived with Lauren at one point or another. We all know you can't utter the word "Heidi" without then mentioning her hubby Spencer Pratt. He's related to Stephanie Pratt (his real sister) and Holly (his sister-in-law). And, he's had some issues with neighbor Enzo and Stacie the Bartender (who Kristin kissed last season in Vegas!).

Finally we're left with sweet-as-pie Whitney Port, who fits in because she worked with Lauren at Teen Vogue. She's now living and working in "The City" with Kelly Cutrone, who once also employed Lauren.
