Beyond my desire to boycott the torture factories, I am also way happier when I eat a plant-based diet, and I feel about a thousand times more energetic.

It would be so depressing to be a model and not get to say a word. There's no personality involved.

Cleanses and products don't make you look more beautiful. They certainly help, but if you reach contentment, you're set. My makeup artist, Melanie Iglesias, couldn't figure out why my skin looks so good. I think it's because I'm happy!

The difference between romantic love and friendship love is that romantic love involves a lot of compromise. It is a very giving type of love. With friendship, you can be a little bit more autonomous. You are not expected to compromise, in the same way. Maybe that's why friendships tend to last longer.

You're 30: You know stuff now. Your 20s were for 'ducking up,' as my auto-correct would say, and learning from those mistakes. (For instance, never again will I convince myself that sleep is for sissies and go straight from a party to the airport. You will not 'sleep on the plane'; you'll vomit in the security line. Go to bed.)

I've always been a fan of science fiction. My family, we all used to watch 'Star Trek' together, which is kind of a nerdy family activity.

When you're in a romantic relationship, of course, there is a lot more compromise and you have to be a lot more unselfish.
