Sienna Miller is no stranger to nudity, but this is the first time we've seen full frontal nudity out of the actress. She's currently filming Hippie Hippie Shake, which seems to include a scene where she gets totally nude and wanders into a lake. Thankfully, someone was on set to snap pictures of her, so we don't have to wait for the movie to come out to access this exciting new masturbatory material.
You can check out the photos of Sienna naked here. Warning: These are totally, completely not suitable for work. Unless you have my job. In which case they are totally awesome for work. (How jealous are you right now?)
