HEIDI KLUM, 40
It's just another day in paradise for Klum, whose bikini bod is just as stunning as her July family vacation spot on Paradise Island, Bahamas. And the mom-of-four (Leni, 9, Henry, 7½, Johan, 6½ and Lou, 3½) says she has those very people to thank for her enviable figure. "I go up the canyon or I go into the backyard, and I jump with my kids on the trampoline," she told reporters of her workout regimen. "I try to put the exercise into my daily routine."
