Justin Bartha is now a married man (on and off the screen).
The 35-year-old Hangover franchise star tied the knot with personal trainer Lia Smith Saturday evening on the island of O'ahu in Hawaii at Kualoa ranch, E! News has confirmed.
For their walk down the aisle, Smith sported a flowy, white gown, while Bartha wore a black suit.
A source tells E! News the intimate ceremony was held in the lagoon at the ranch and the reception was held in the valley, where Hunger Games was coincidentally filmed.
The duo kept their wedding small, with no more than 20 people in attendance—two of whom were Reese Witherspoon and her hubby Jim Toth, who flew in for the wedding Friday.
The blushing bride is originally from Hawaii, where she and Bartha were first publicly linked on New Year's Day in 2013.
The private couple didn't announce or confirm news of their engagement after Bartha popped the question last May in Big Sur, Calif., but rumors started to surface that the duo was set to tie the knot after Smith stepped out rocking a diamond sparkler on her ring finger that month.
A source told People at the time Bartha and Smith were "very happy."
This is the first marriage for the actor, who previously dated Ashley Olsen for two years before splitting with the former Full House star in early 2011.
Here's hoping Bartha didn't run into any of the pre-wedding fiascos his character, Doug, faced in The Hangover.
Congrats to the couple!
