The "Twilight" leading lady, Kristen Stewart, has no qualms about getting downright naked and dirty. Stewart did have a few notable bed scenes in the latest "Twilight" saga installment, "Breaking Dawn". In fact the nudity doesn't stop there.

For the 2012 Cannes Film Festival, Kristen Stewart goes topless for a few scenes in "On the Road". Going completely topless wasn't even a big deal because in one scene, Kristen had to be completely naked opposite Garrett Hedlund.

"I genuinely did feel so completely comfortable that watching it now even I'm like 'Whoa!,'" explained Stewart

"which is fine, that's the way I should react to it. I'm so not like her, as I've said, but um..." quipped the actress

"Our first day of shooting was answering the door naked and her being in bed over there. But you know, the characters you're playing. You just go for it." said co-star, Hedlund.

Given Kristen's film history of going topless in "Adventureland" opposite Jesse Eisenberg and being a stripper in "Meet the Rileys", which is why nudity isn't a touchy issue for the 22-year old star.

In an interview with E! Online, Kristen sheds light on her comfort issues about being naked for the camera and how people would react to her topless scenes.

"People are really predictable," said Stewart during the MTVs Sneak Peak at "Snow White & the Huntsman". "I completely expected that," continued Stewart.

The same thing goes for Stewart's' longtime beau, Robert Pattinson. In Pattinson's newest film, "Cosmopolis", the 26-year old bares "ball"-worthy scenes - literally.

"Five minutes before we filmed, David [Cronenberg, director] told me, 'I want to see the bottom of your balls on the top of the frame'. At the moment, I reminded myself that I would do anything for him. So I went back to see him and told him that wouldn't happen. He took it really well. At the start, it's a very bizarre scene that you won't see again in another movie, I promise," shared Pattinson

Nudity really isn't an issue for the "Robsten" duo and it is most definitely not a problem for their fans as well. When it comes to the film industry, Robert and Kristen just dive in head first because the films aren't only for their fans but for themselves as well.

"But it's like, 'Well, are you making movies to be successful? Or are you making movies to learn something?' It makes sense because it's hard to remain successful in Hollywood without figuring out what your path is...But I haven't done that. I just got really lucky," says Kristen.
