The fun didn't end when the catwalk closed at last night's Victoria's Secret Fashion Show. From there, the Angels traded their lingerie and wings for a bevy of sexy cocktail dresses, then headed to NYC's Lavo for the afterparty. There, the cast of Angels, including Karlie Kloss and Joan Smalls — who traded their runway looks for a sparkly silver number and a very sexy mesh mini — was joined by the night's big performers, like Justin Bieber and Rihanna, as well as a slew of celebrities who helped keep the party going. Poppy Delevingne stepped out to support sister Cara, while Alexa Chung and Vanessa Hudgens were on hand for all the festivities.
