Ron Livingston has tied the knot!

The actor tied the knot with his former Standoff costar, Rosemarie DeWitt, on Nov. 2, his rep tells

Livingston, 42 — who is likely best known for his role in Office Space and his turn as Sarah Jessica Parker's beau in Sex and the City — met DeWitt while shooting the short-lived Fox series.

Shortly before they began dating in 2006, at a TCA panel before Standoff's September premiere, DeWitt addressed their characters' on-screen chemistry.

"I like Ron," the Rachel Getting Married star, 35, said. "I think it helps when you just like somebody as a person. He is a good guy to have on your team. We like running lines in the trailer and figuring out a scene."

Livingston added that they trusted each other completely and had "each other's backs" at all times.

"It’s a little bit like dancing," he said in 2006. "Really good dancers — sure, the guy’s leading, but he’s leading to where he knows that she’s going to go really well and takes a lot of cues off her."
