We got to travel back in time for last night's episode of The Hills , with the return of Lauren's high-school, on-again-off-again lovah Stephen Colletti. Lauren and company moved into a sweet new pad, which of course required a housewarming party. The girls broke out their sexy dresses and mingled with their odd mix of guests. Take our quiz to see if you picked up on the fun fashion details and take Bella's for beauty trivia !
