Cover appearances: 1998
Supermodel Heidi Klum is no stranger to skimpy, sizzling photos, and her 1998 appearance on the world-famous issue was no different. The 39-year-old Victoria’s Secret Angel swears by yoga, boxing, and running, along with regular workouts with David Kirsch to stay bikini-ready all year round. “I represent more the healthy, happy, curvy, strong woman. And that sounds much healthier to me than being 80 pounds and skinny as a bean,” she says.
