I don't work with a trainer. I just go to cheerleading practice and run a couple times a week.

Most days I don't care what I wear. You'll find me in yoga pants, a T-shirt, and sneakers almost every day. My job is to wear something nice when I work, so I enjoy doing it then. But when I don't have to, I'd rather just wear something comfortable.

A lot of people are like, "Oh, it's so much easier to be a supermodel now because you have Instagram. You don't even need an agency anymore." But that's just not true. I still had to go to all the castings, I still had to go meet all the photographers, I still had to do all of that to get to where I am now. There wasn't a step taken out just because I had social media. I still have 12-hour days, I still have even 24-hour days sometimes; I still have to do all those things. We don't work any less hard than the '90s models did when they were young.

I remember being backstage in my full look and the make-up artist said to me: ‘Did you hear? Kendall Jenner is here.’ ‘And I said, ‘She is? Oh my God!’

Every makeup artist has a straw somewhere on them, pretty much at all times. They're pros, and it's a lot easier to sip things backstage and not mess with your lipstick that way. You learn fast to always ask for a straw when your makeup is done.

I'm obsessed with Tumblr. I love looking at all the pictures!

I think mascara is a must. If I'm going to wear makeup somewhere, and I'm doing it, it's usually really simple - it's just mascara and maybe a tiny bit of eyeshadow, but that's it.
