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.
With the Teton Mountains as a backdrop, the couple were joined by 80 family and friends – including some of the actor s NCIS: LA costars.
Olsen and his groomsmen wore Calvin Klein linen pants, J. Crew sun-bleached oxford shirts, Oakley sunglasses and TOMS shoes. Wright, 29, glowed in a J. Crew wedding dress, while her bridesmaids wore dresses from Ivy & Aster, paired with Oakley sunglasses.
At the tented reception, a bluegrass band provided the entertainment while guests dined on barbecue, played horseshoe and beanbag toss and made s’mores at several fire pits on the 40-acre property. Instead of a traditional wedding cake, the couple served their favorite dessert – Whitey’s Ice Cream – which they had FedExed from Iowa for the special day.
Olsen proposed to Wright, who stars in the upcoming feature film 21 and Over, while on vacation last year in Punta Mita, Mexico.
This is the first marriage for Olsen and the second for Wright.
