Natalie Portman has posed naked for a Dior advertisement to promote the brand’s new Diorskin Nude range, which promises a more natural look. In one of the pictures, the sultry actress has been snapped lying topless over a chaise lounge pulling her hair off her face. In another close-up shot, the brunette beauty is facing the camera with her arms and hair covering her chest to protect her modesty, the Daily mail reported. The Black Swan star, who married Benjamin Millepied in a traditional Jewish ceremony at the weekend, has bared all for brand earlier too. In a 2011 advertisement, the brand’s ambassador wore just a black headband to promote the fashion house’s fragrance ‘Miss Dior Cherie’.
