The doctors say it dates back to a film where I had these huge prosthetic breasts because my character was breast-feeding. The weight of them, and of the baby, did my back in.

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.

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

People became more interested in my love life than in me, and that has a certain effect. You start to feel very empty and worth nothing, you start to become a piece in a board game you never wanted to play.

I'm in a really good place. I used to be a right worrier, but being in a settled relationship has made a massive difference. I was on my own for three years before meeting David. I'm very happy with him, he's a fantastic man. But you never know what's around the corner, so you just hope for the best.

I was just disciplined. I knew I had to get back into shape after six weeks for the film Goal II, but I cheated in the end - I wore a corset. I loved my pregnancy, I blossomed. I felt goddess-like and very secure. I found it comforting to have a little thing growing inside me, and very calming.

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