After completing a recent stint in rehab, Laguna Beach bad boy Jason Wahler apparently feels matrimony is the next logical step.
The reality star got engaged to his girlfriend, USC freshman tennis player Katja Decker-Sadowski, on Saturday, his rep confirms to E! News.
Wahler, 20, popped the question to Decker-Sadowski, 19, during a housewarming party at their shared Los Angeles home, with friends—including former flame Lauren Conrad—looking on.
According to People, he gifted her with a four-carat emerald-cut diamond from XIV Karat in Beverly Hills.
No wedding date has been set.
Wahler's decision to settle down comes in the wake of four drinking-related arrests in less than a year.
In March, he was sentenced to two months in jail for punching a Los Angeles police officer, but a judge suspended his sentence after he checked into rehab in May.
Earlier this month, the same officer filed suit against Wahler and former gal-pal Kristen DeLuca, claiming the couple roughed him up while screaming racial epithets as he tried to assist a tow-truck driver last year.
Jonathan Wallace is asking for at least $200,000 in damages for assault, battery and violation of his civil rights.
Neither Wahler nor DeLuca has commented on the suit.
Aside from planning his nuptials, Wahler is due to put in an appearance on The Hills on Sept. 10. He'll also be seen in MTV's new show, Celebrity Rap Superstar, which airs live on Sept. 30.
If he's still looking for work after that, he and his new fiancée could always consider starring in an episode of the music network's true-life series, Engaged and Underage.
