My thighs were huge; they were like rock! Growing up, I was really athletic, and I had a very athletic body.

I usually do my hair and makeup in 30 to 45 minutes, and if my hair is dirty, I'll just put it in a bun or a ponytail. If it's in a bun, I'll part it down the middle and do a low bun with a couple pieces in the front coming down.

My Pirelli calendar is hanging on the wall of my friend's frat house, and he doesn't know anything about fashion. That balance is what leads to big campaigns outside of fashion. But I never want to choose one or the other. Both commercial and high fashion are what make my job so interesting.

I will be the first to say, when I started, I was the worst on the runway ever. I feel like I try to keep learning every time I step off a runway; I try to get better with each one. I hope that I'm getting better as I go - it takes a few seasons to get your Karlie Kloss walk on.

When I started at 'SNL,' I was lucky to start early. So now starting on 'Update,' I am the age when most people are when they start doing that. It feels like a different world and capacity, like starting over in another challenge. A heightened challenge.

Keep on beginning and failing. Each time you fail, start all over again, and you will grow stronger until you have accomplished a purpose - not the one you began with perhaps, but one you'll be glad to remember.

A part of growing up in this international world is understanding and being prepared and having tools to adapt outside of the small environment that you may have come from. That's what education is all about.

This has not changed: always like the first time, very, very nervous. But when the music begins, you are in the music, it's a sort of transformation. Your feeling for the music is greater and has nothing to do with your nerves. You go out of yourself.
