The day I finished 'Twilight,' I came home and started bulking up. For 'New Moon,' I'm 30 pounds heavier than I was in 'Twilight.'

I love challenging myself, doing different things and exploring different areas that I haven't been to or gone to before. That's what I love about acting, and that's what I love about film.

I don't want to become known as just a body.

When I went to Australia, I went shark diving. It was crazy. It was called 'extreme' shark diving because even though we were in cages, we literally could touch the sharks swimming by. They were huge and I'm terrified of sharks. Then I went to a wildlife park and held kangaroos. That was nice.

The actual getting into the gym and working out process was easier, but the eating was harder. I had to eat every two hours. At one point, my trainer said, 'Put anything in your mouth. Go to McDonald's, get the biggest shake possible. I just need to get calories in you.' Because my body fat at the time was only, like, seven and a half percent.

Honestly I try to stay away from what has been written about me because if you let that stuff get to you and it's not true, it can drive you crazy.

I was not a vampire or werewolf fan at all. I'd never even heard of the series. I auditioned for the role, and as soon as I got it, I started reading the books. I'm not a reader, but I really did get hooked on them.
