In a picture perfect East Coast wedding, Heroes actress Ali Larter wed her longtime actor beau Hayes MacArthur at his family estate in Kennebunkport, Maine on Saturday evening, her rep confirms exclusively to PEOPLE.
Under a canopy of trees late in the afternoon, the bride, 33, dazzled in a Vera Wang sweetheart neck, A-line gown of Chantilly with hand-pieced corded lace appliqué, while her groom, 32, wore a Ralph Lauren Black Label peak-lapel tuxedo and Polo Ralph Lauren bow tie.
Larter walked down a grassy aisle lined with purple, pink and white flowers and carried a simple matching bouquet as guests looked on. The bride wore a pair of satin platform sandals by Jimmy Choo.
They were engaged in December 2007, and later that year Larter, 33, spoke about her husband-to-be saying MacArthur, 32, “brought light to my life. I feel lucky every morning when I wake up and see him.”
