If there's anyone who's living proof that age is just a number, it's Heidi Klum!
The 40-year-old mother of 4 recently graced the cover of Women's Health magazine, and with just a tiny peek at her tightly toned tummy, it's easy to see why she was the perfect choice!!
But how does Heidi manage to keep her abs in such MILF-tastic shape?? Well, she says a big part of it is maintaining a healthy diet, however, just like the rest of us she faces her fair share of temptation!
