Sexy vampires ruled the red carpet at last night’s 12th Annual Young Hollywood Awards in L.A. The Twilight Saga‘s Ashley Greene, who fittingly took home the Style Icon award, dazzled the crowd in a gorgeous peek-a-boo Antonio Berardi dress and Irit Design earrings while The Vampire Diaries star and Making Their Mark winner Nina Dobrev was the ultimate glamour girl in a strapless black-and-white design by Naeem Khan. The boys also made a stylish impression—Artist of the Year Nick Jonas hit the red carpet in a dashing gray three-piece suit while bro Joe Jonas put his own spin to his suit with a sharp fedora.
