Kristen appears in a feature in the February 2013 issue of W. The magazine, which fronts Emma Stone on the cover for the "Movie Issue," features Stewart posed with her signature nonchalant face expression dressed in a studded strapless top by Isabel Marant. In the image, Stewart is more like herself off-camera; she was photographed sans makeup with tousled hair worn on one side.

After Stewart, 22, showed her sexier side in the film "On The Road," the magazine asked her to share her feelings about shooting in the nude on-camera. The actress also discussed the fears she had during the film's production.

Stewart said reporters always "ask about the nude scenes in 'On the Road'," but she had to remind them that she had to dance as well in the film and it wasn't an easy feat.

"I also had to dance, and dancing is harder than being naked," Stewart said. "We did the dance four times to the song 'Salt Peanuts.' By the end, I was as red as a fire truck. I was holding onto Garrett [Hedlund] because I was going to fall over. I almost passed out every single time."

Stewart enjoyed playing her character, a freespirited girl named Marylou, who sleeps with the two male characters she goes on a road trip with. She admitted that although she admired Marylou, it was a challenge to act out a scene that lived up to the book which the film was inspired by.

"My character, Marylou, is so exuberant, and I had five minutes to do something that showed she was sort of like the craziest motherf*cker around. In the book, it says, 'Dean takes Marylou and they do a love dance and no one can take their eyes off them.' It's one sentence. And I was mad-intimidated by it."

The February 2013 issue of W magazine featuring Kristen Stewart is out on newsstands now.
