As BFF to Paris Hilton, Kim Kardashian is no stranger to the limelight, but until last week, she had never set foot on a runway. Making her debut at long-time friend’s Christian Audigier’s (who also designs Madonna-fave Ed Hardy) show during L.A. Fashion Week, it was hard to believe she wasn’t a seasoned pro. But unlike Paris, the owner of L.A. boutique Dash experienced fashion show jitters, telling PEOPLE, “I’m not a model. I was really nervous. It was nerve-wracking — but I did it!” And luckily she made it through without any spills.
