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!’

I used to have the craziest fear of losing teeth. I would have nightmares about that all the time. But it's the craziest thing, because I feel like that's one of the easiest things to fix. You just get veneers or something.

I'm not super open to new people. I have a small group of people I trust. I'm very intuitive, so I'm good at feeling out how people are, like if they have bad intentions. Sometimes I'm very closed off, which annoys me, but I think it's for the best.

If I could trade places with any of my sisters for a day, it would be Kim. I want to see what it's like...The only time she sleeps is on the airplane. It's just crazy. I feel bad for her, but I still want to know what it's like.

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.

I feel like I grew up too fast a long time ago.
