"They don't make them any better than Justin, and I could not be more thrilled to officially be Mrs. Hartley!" Stause told People Magazine.
The wedding took place at Calamigos Ranch in Malibu in the U.S.
Hartney's TV mom Mandy Moore was one of the first guests to arrive, reported E! News.
The groom wore a navy tuxedo and a bow tie, while the bride wore a Monique Lhuillier dress with spaghetti straps and a big poofy feather skirt.
During the vows, Stause promised to always be there for Hartney "just like the Dodgers in the World Series," spurring laughs.
Stause and Hartley, who have been dating for four years, got engaged last summer.
This is Hartley's second marriage, who was previously married to actress Lindsay Korman. (ANI)
