The thought of attention made me want to hide in a closet. I wasn't a kid who liked attention. I liked solitude and I still kind of do.

When I was a kid, I was always around boys. I was always trying to keep up with boys - skateboarding and snowboarding. If my brother was mowing the lawn, I had to mow the lawn. If my brother was using a hammer, I needed to use a hammer. I've always been a little bit of a feminist.

Modeling's terrifying to a lot of people. Standing in front of a camera is terrifying. I like a challenge.

I remember one of the first things Helmut Newton on one of his last shoots, in 2004, said was that he couldn't believe how thin I was. He was like, "Whatever happened to women?" He also made me wear rubber nipples. It was amazing to be in a situation where you have to create but you don't feel any pressure. He had such confidence that it made things really easy. There's a natural sort of process of something coming to life, which I really liked. It was like, "We're here, and let's make you lay on a bed of nails." But it didn't seem contrived or overly thought-out. It was easy.

Sometimes I am still surprised that I'm a model and that people think I'm good-looking.

And of course there is nothing better than wearing the same T-shirt for days and not brushing my hair for weeks.

Words are difficult and photography takes the words away from things. It's difficult to talk about something that seems to come very naturally to you, to explain a process. A moment is really difficult to put on paper.
