Wahler and fiancee Decker-Sadowski called it quits in 2009. The party boy was arrested six times for alcohol-related offenses and cleaned up his act on VH1's Celebrity Rehab in 2010. He proposed to model Ashley Slack in November 2012; she posted a picture of the ring on Instagram. "This is the first relationship I've ever been in sober," Wahler tells Us Weekly of Slack. "It's a little bit different when you're not drinking and going out. She's my best friend."
