Jason Wahler may have cultivated a bad boy image during his stints on MTV's 'Laguna Beach' and 'The Hills,' but in his most recent foray into reality TV -- VH1's 'Celebrity Rehab' (season finale Wed., Jan. 12, 10PM ET) -- Wahler made a conscious effort to keep a low profile during filming.

"I wanted to show that I was taking my problem seriously," Wahler told TV Squad. "I was revamping myself and showing everyone I'm not drinking."

Wahler was arrested six times for alcohol-related offenses in the last few years before checking into the Pasadena Recovery Center with Dr. Drew.

Pretty soon, you'll be seeing the kids from MTV's Laguna Beach: The Real O.C. all over the place. Six of them (Alex Murrel, Jason Wahler, Lauren Conrad, Stephan Colletti, Kristin Cavallari and Tallan Torriero) are part of a new advertising campaign by BONGO clothing that launches in fashion, entertainment and lifestyle magazines this Spring. The concept behind the campaign is a party. BONGO rented out a ritzy mansion in Orange County and let the kids do their thing as the band, The Colour, played on set. Alex Murrel, who has an album coming out this spring (who doesn't?), joined the band while the boys pushed each other into the pool, proving that they are barely out of high school. The Laguna clan replaces an ad campaign last year by BONGO that featured Nicole Richie and her ex-fiance, DJ AM.
