L.A. Fashion Week

Lauren Conrad, whose life as a fashion student and intern at Teen Vogue has been chronicled on MTV's "The Hills," turned her focus from the show to the runway this week. Conrad debuted her fall collection at Los Angeles Fashion Week. "Hills" stars and former Conrad foes were at the event to help celebrate the young designer's first line.
