"You have to have the courage to stand up for what you believe in – no matter how hard it is – as your beliefs make you who you are amid all the celeb madness. I'm a vegetarian and never wear leather or use products tested on animals. When I was just starting out I'd get a gazillion freebies thrown at me, so it was hard to know what contained what. Now, I've made sure that before I get to a photoshoot people know my stance on that."
