After recently finishing treatment for an eating disorder, it appears that Mary-Kate Olsen is embracing food again. In fact, she and sis Ashley just became spokestwins for McDonald's in France. Specifically, they've been promoting McDonald's Happy Meals, which not only include French fries (they call 'em frites), but also prizes like a photo album, a denim bag or a crayon box bearing the Olsens' names and photos.
