Kristen Stewart has stripped down to her underwear to film a skinny dipping scene for her upcoming film 'Sils Maria.'
The 23-year-old actress was snapped wearing a black bra and white underwear, as she was filming the scene with co-star Juliette Binoche, Us magazine reported.
The 'Twilight' actress was sporting a tattoo below her right elbow for the role, as Binoche appeared to go completely nude.
The film, which is directed by Olivier Assayas, features Stewart in a supporting role as Binoche's assistant.
