Fans of The Hills can rejoice because OG bad girl Kristin Cavallari, 33, is ready to return to the show that made her a star. Of course, her life has changed dramatically since her time on the beloved MTV show over a decade ago. She’s now a married mom of 3 and a fashion mogul, with her own show, Very Cavallari, on the E! network. But that doesn’t mean she’s not interested in taking a trip down memory lane.
