Eric Christian Olsen is officially off the market.
The NCIS: Los Angeles star tied the knot with his longtime girlfriend, actress Sarah Wright, on Saturday near Jackson Hole, Wyo., his rep tells PEOPLE exclusively.
“You hear people talk about cold feet, but there was never a moment of doubt with Sarah because no one makes me happier, no one makes me laugh more, and I can’t imagine a better mother for our future children,” Olsen, 35, tells PEOPLE.
The couple, who met in 2006, exchanged vows during an evening outdoor ceremony performed by Olsen s father, Paul, on the grounds of the Wyoming barn the actor bought and remodeled with his family and Wright.
