HEIDI KLUM

Less than two months after welcoming baby No. 4, Lou Sulola, the model, 36, had lost 25 lbs. with light medicine ball workouts and a "carb break," she says. "I still have 20 lbs. to go, but there's no master plan." Still, the sexy mom was svelte enough to walk the runway at the Victoria's Secret Fashion Show. "I embrace that I have more curves now," Klum said.
