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.

I've been onstage once for one performance with four days' rehearsal.

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

Well ironically my last three roles have all been a mother. One was a Canadian film where the baby was taken away because she is a drug addict, in Irish Jam I play a mother to a four year old. I think in the future I'll be able to handle the role with a lot more depth.

In Hollywood I got work but not the right work until Pushing Daisies. Every girl in LA wanted the part of Chuck. I was terrified - I didn't know if I could be funny.

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.

If oil exploration can threaten a place as beautiful and meaningful as Virunga, where next?
