Kristen Stewart was on set for Sils Maria, losing clothes and taking a dip in the process! Kristen and her costar Juliette Binoche were filming at a lake in Switzerland recently, and both actresses ditched their clothes and took to the water. Kristen has worked on the project for the greater part of September, and she filmed scenes in Berlin a few weeks ago. Prior to that, Kristen suited up in military fatigues to shoot Camp X-Ray back in July. New movies aren't the only thing on Kristen's plate right now, either! She also bared all for a new Balenciaga fragrance campaign called Florabotanica. Take a look at the hot new set pics!
