I stay out of the sun, and if I'm in the sun, I'm wearing SPF. I protect my skin as much as I can; I learned that a long time ago. I also exercise every day and I get the endorphins going. It's important not only for my physical self but also for my mental self and my emotional self. I'm healthy, I eat well most of the time, I take care of myself and I drink a lot of water. But I also enjoy myself. Taking care of yourself doesn't have to be painful, it's about finding the right balance, I think.

Singing is a way of releasing an emotion that you sometimes can't portray when you're acting. And music moves your soul, so music is the source of the most intense emotions you can feel. When you hear a song and you're acting it's incredible. But when you're singing a song and you're acting it's even more incredible.

I did theatre when I was nine, I think. Nine and ten, and that was just the beginning of my whole involvement in acting, my whole interest. I don't really remember it that well. But it was really fun. I mean, it was exciting just to be on stage in front of an audience. It gives you a different kind of rush.

I have a dirty mouth sometimes, and I'm very liberal, and that doesn't always go down well in the film industry - especially when you've got to appeal to mums and daughters.

It's really easy to avoid the tabloids. You just live your life and don't hang out with famous people who are in the tabloids. Don't do anything controversial and be a normal person. Have friends. And get a job and keep working.

Marriage, at this point in my life? I'm not interested in it. Yet. Maybe later when I'm 35 or 40.

The main thing you can change is how you perceive yourself. Stop looking in the mirror and realize that you're living for yourself, not other people ... I have belly fat like everybody else, and I don't want to be airbrushed on the cover of a magazine. I don't want someone to swap out my stomach with a supermodel. I don't want dirty old men looking at me in my underwear.
