When I'm working, it's those actors (you know who you are) who sit around moaning that their trailer isn't big enough, or how bad their facilities are. I can't be doing with any of that, I just like to get on with it.

There were reports of me using fat-sucking machines and all sorts of silliness. All I did was walk a lot and breast-feed. I've never been on a strict diet. I just don't overeat, and I don't eat if I'm not hungry.

Being a mother gives you an incredible feeling of empowerment, you think if I can go through such pain and that level of sleep and still operate and not be grumpy you can do anything. It can be quite scary, you can't function your brain, forget your vocabulary.
