I think people are uncomfortable seeing pregnant women, particularly with any kind of conflict. [Pregnancy is] very much a projection of life and love, but it's also very complicated. People have very complicated pregnancies. They could be accidental or people suffer depression, and that was a really interesting thing for me. And a challenging thing. I have not been pregnant. I don't know what that's like, let alone to be really conflicted about it. Acting in the film about pregnancy was a really interesting thing to do.

TV is a completely different discipline, which I think I am still learning about. You just have to learn how to work fast and pace yourself.

The British are so funny.

What has surprised me most about being a celebrity is the fascination with pregnant women. After I had Rocco, the paparazzi came and sought me out. I never had that before. There's a whole industry, literally, based on people having children. I guess because you're changing, putting on weight. It makes me very uncomfortable. I didn't enjoy that much at all.

My parents weren't in the arts, but we grew up in Balmain, which at that time was an artistic, bohemian suburb of Sydney. It's a lot more gentrified now. It was very working class, pubs on every corner because it's right by the water so a lot of the guys on the ships and the boats used to go and drink there. It's very posh now.

Where I am now, you're very much at everybody else's mercy. You have no control over your career in a lot of ways. It's just important to know what your own goals are, because that's empowering.

Healthy aggression is good, but I think social media can perpetuate that in the worst way. You have to be careful about comparing yourself to others. You can never be somebody else. You will only be yourself, and that's what's great.
