Yes, she wore a white wedding dress – and it was Armani!
The actress, 24, walked down the sandy aisle to meet her groom outside the Four Seasons Resort Hualalai at Historic Ka’upulehu, and they were wed by a local kahuna, a Hawaiian priest. Kassius (whose mother is Green’s ex, Vanessa Marcil) was also the groom’s best man, and sported a jade bracelet blessed with ocean water.
Fox’s Armani Privé gown featured a 16-ft. train. Her husband also wore an all-white Emporio Armani ensemble for the ceremony.
“They were beyond happy, and they seemed so comfortable,” a friend of the couple’s tells PEOPLE. “They decided a long time ago that they belonged with each other.”
