Hollywood's A-list stars have gone make-up free for W Magazine's February 2013 issue.

Glamorous actresses like Twilight star Kristen Stewart, Academy Award winner Nicole Kidman and French beauty Marion Cotillard are seen in natural colours, in a series of photographs by Juergen Teller.

Other actresses caught so on camera include Zero Dark Thirty's Jessica Chastain, Naomi Watts (who plays the role of the late Princess Diana in a forthcoming feature) and the Pirates of the Caribbean's Keira Knightley.

And it isn't the just the women who've stripped the cosmetics off their faces. Academy Award winners Daniel Day-Lewis and Philip Seymour Hoffman, Skyfall star Javier Bardem and comic actor Jack Black are also included.

W Magazine's Best Performance feature has the 22-year-old  Stewart, whose romantic saga with former Harry Potter actor and Twilight co-star Robert Pattinson has been well-documented, speaking about one of her newer films - On The Road - which is based on the classic American novel by Jack Kerouac.

"Everyone asks about the nude scenes in On the Road, but I also had to dance, and dancing is harder than being naked. My character, Marylou, is so exuberant, and I had five minutes to do something that showed she was sort of like the craziest motherf****r around," the Los Angeles-born actress said.

"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. 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," she continued.

Meanwhile, the 55-year-old Daniel Day-Lewis, who received the Golden Globe for Best Actor (Drama) for his role in Lincoln, said he enjoyed working in the film.

"I miss playing Lincoln. Very much. I miss the proximity to his character. There was a time in my life when it wasn't clear whether or not I would amount to anything. I was fearful about my future. In England, people were hell-bent on certifying me-to them, the way I work as an actor is the system of someone who is unhinged. As a young man, when I saw the early movies by Scorsese, I saw a way to be, a kind of liberation. In those movies, America seemed like a place of infinite opportunities. In Lincoln, we tried to show that sense of grand democratic possibility. We created a world I didn't want to leave," he told the magazine.

The cover for the February issue belongs to the youngest star in Hollywood - nine-year-old Quvenzhane Wallis - of Beasts of the Southern Wild. Wallis has been nominated by the Academy Awards in the Best Actress category. And should the young girl win the award for her debut role she will become the youngest ever to win the award. She is already the youngest person to be nominated

"When I watch a movie, I think, Not her, not her. I should have been in that movie! That's my part. Why can't they have a little sister? Why couldn't they put me in that? I get so mad and frustrated. But it's actually very funny to me that people cry at my movie. Especially the ladies­-their mascara falls down and down and down," Wallis said.

W Magazine's feature brings to mind comments made last year by UK model Lily Cole, when the 25-year-old spoke out against the fashion and model industry piling unnecessary pressure on young women. Cole also shared her experiences on the pain of constantly looking glamorous.
