It looks like Justin Bartha survived his real-life bachelor party just fine.

The "Hangover" franchise star married fitness instructor Lia Smith on Saturday afternoon in Oahu.

Reese Witherspoon and her husband, Bartha's agent Jim Toth, attended the festivities at Kualoa Ranch, as did Jesse Eisenberg and the actor's "Hangover" co-star Ken Jeong.

Smith wore a simple, flowing gown with spaghetti straps and a sweetheart neckline and tucked a few white flowers into her updo hairstyle. Bartha was dapper in a navy blue three-piece suit.

Hawaii has been an important place for the pair. Not only is the bride from the stunning state, but Bartha, 35, first took his relationship with Smith public in January 2013 when they were photographed together on a beach in Maui.

The two first met several months prior in a Pilates class at Equinox in Los Angeles. They were engaged while on vacation in early May when Bartha popped the question at the Post Ranch Inn in Big Sur, California.

Bartha famously dated Ashley Olsen for two years before they parted ways in March 2011. He was also briefly linked to Scarlett Johansson.
