"We’re lucky [working hard] comes quite naturally for us," the 30-year-old said of her and her sister's work ethic. She continued, "But then I have a husband, two step-kids and a life; I have to go home and cook dinner. I ride horses on the weekends. You find the thing that helps you relax and if you don’t have it, you have to look for it." This is possibly the most Mary-Kate has ever said on the subject of her husband, who happens to be the half-brother of former French president Nicolas Sarkozy.

But this talk of their home life is new — it's so lovely to hear that the high-profile couple enjoys a low-key life.
