Mary-Kate explains all the hiding

Mary-Kate Olsen explained the logic behind her oft-hidden face in paparazzi pics. "I don't want my picture taken," the 21-year-old told Entertainment Weekly mag. "The only time I think it's okay is at a red-carpet event or a photo shoot. So every time I see a paparazzi, I cover my face so they don't get a picture, and I'm just 'the mean person who doesn't smile.' I would love to be able to swim in the ocean in Malibu," she says. "But that is asking for a bikini shot. That's inviting something that I don't want to happen. I don't need to be on a 'Who's Skinny, Who's Fat, Who's Looking Healthy, Who's Not Eating?' list." Olsen's 10-episode arc on Showtime's Weeds begins September 17.
