However, on the new episodes of the Hills, a now sober Stephanie enrolls in the Fashion Institute of Design and Merchandising and finds herself studying alongside her brother’s ultimate nemesis: Lauren Conrad! Be prepared to watch the Pratt siblings fight, as Stephanie becomes gal pals with his girlfriend, Heidi Montag’s, former friends.
