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.

But Americans find me bizarre and always ask me why I eat so many carbs. I tell them I don't get full otherwise.

I look at being an actress as being like a mummy: You're bandaged up and preserved as soon as you start making other people money.

I have the most lovely, healthy bouncing baby, she was all very compact and the right size.

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.

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.

It's so important to raise awareness of this problem that continues to affect 1 in 4 women at some point in their lifetime, regardless of career, wealth or background.
