The actress, 29, tied the knot with Adam Shulman, 31, on Saturday night in scenic Big Sur on the California coast, PEOPLE confirms.
More than 100 guests were invited for the wedding weekend, which started Friday with a rehearsal dinner at the Ventana Inn and Spa. A nearby private estate was secured for the ceremony. And Valentino provided a custom gown, the designer confirmed last week.
The wedding décor was inspired by nature, with many branches used to create a ceremony and reception to blend in with the majestic Big Sur surroundings, a source tells PEOPLE.
The couple, who have been together four years, got engaged last November.
"I am very much in love with him, [only] Adam totally ruined my plan," the star of the Princess Diaries and the upcoming Les Misérables said last year of their relationship. "I was really actually looking forward to a little alone time, and then I fell in love like a fool!"
