‘Twilight’ actress, Kristen Stewart, is taking on edgier roles outside the vampire series. In two movies, Welcome to the Rileys and The Runaways, both screening at Sundance, Stewart appears in various states of undress. But in one case, she’s not as naked as she looks, she told MTV. It’s amazing what the movies can do.

In Rileys Stewart, 20, plays a teen stripper/prostitute, who falls under the fatherly eye of a man, played by James Gandolfini, who has lost his own teenage daughter. She appears onscreen in skimpy outfits and, once or twice, without clothes on.

The 20-year-old explained to MTV that acting gives her the strength to do things she might not otherwise. She said, “There are things you are capable of doing under the guise [of acting]. You’re so safe.”

Also, in the final shot of Runaways, in which she plays real-life rocker Joan Jett, Stewart is seen floating underwater without any clothes on, or is she?

“You can’t see anything,” said Stewart,  adding that she was not actually unclad. “I was not naked,” she said. “I was wearing stuff. I was wearing really, really, really unattractive nude moleskin or something. Really, really, really gross. In the movie, it’s like, ‘Oh, it’s cool, this looks objective. She’s submerged. She’s lost in this world, this ocean.’”

Stewart also told MTV she wasn’t clear on what floating nude in the ocean had to do with the story but, under the direction of Floria Sigismondi, she went for it anyway.

“I was like, ‘What is this? I’m in a bathtub and suddenly I’m in an ocean. I don’t understand. OK, I’ll lay in the water and look like a tool.’”
