So how does the 27-year-old Dutch stunner stay in such great shape? Well, being a mother certainly seems to help. "I have a son so I'm always running after him," Kroes explained. "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."
Of course, the supermodel also admits to a very strenuous exercise routine: "I box, I jump rope, and I do lots of leg work, you know, to keep the butt up. So, it's lots of things. I have an amazing trainer and I'm really fortunate to have that, you know? But it's also my job. You can't compare my life to somebody who goes to work everyday; I have to look this way."
