Natalie Portman has made such a good show of being low-key and private, with that 60-person wedding and all. But for her latest Dior ad, she's basically naked, with the exception of something pink and satiny covering her bottom. We suppose it makes sense, as the campaign is for Dior's latest makeup collection, Nude. At any rate, it looks like she's still in stabbing Mila Kunis Black Swan shape. In fact, we like to imagine that she and hubby Benjamin get Lycra-ed up and have dance-offs in their living room.
