Ali Larter marries longtime boyfriend actor Hayes MacArthur

Heroes star Ali Larter wed actor Hayes MacArthur in an intimate ceremony yesterday at his parents’ estate in Maine.  The newlyweds, both 33-year-old, costarred together in National Lampoon’s Homo Erectus, and announced they were engaged in December 2007 after five years of dating.

Guests arrived at the wedding on trolleys with the ceremony taking place outdoors on the lawn, Usmagazine reports. Irish music played before the ceremony in honor of the groom MacArthur’s heritage.  Actress Amy Smart, of Starsky & Hutch and Road Trip fame, was among the guests.

Larter walked down the aisle with her dad.

It was the first marriage for both.
