So how does the 28-year-old Dutch stunner stay in such great shape? Being a mother certainly seems to help. "I have a son so I'm always running after him," Kroes said. "He's started walking and so that's lots of work. And my priority is really towards him, so I cook for him and then I just munch a little bit and I don't sit down to eat until later."
She also works out regularly. "I box, I jump rope, and I do lots of leg work, you know, to keep the butt up," she said. "So, it's lots of things"
