Molly Sims Marries Producer Scott Stuber

Molly Sims has tied the knot with producer Scott Stuber.

Stuber and Sims dated for a year-and-a-half before he popped the big question in May. The couple exchanged vows in front of friends and family in Napa Valley, Calif., on Saturday, her rep confirms.

Sims, 38, wore a dress by Marchesa and jewels by Lorraine Schwartz, while her man, 42, sported a suit by Tom Ford. Guests, including Vince Vaughn and Josh Duhamel and wife Fergie, enjoyed red velvet cake at the reception.

Sims has never been married, while Stuber is once-divorced, but one thing the couple do share? Work ethic! Sims, a supermodel-turned-actress, is next hosting Project Runway spinoff Project Accessories. Stuber, who has produced flicks like The Break-Up and Role Models, has 40 projects -- yes, 40 -- in the works!
