My whole family is quite petite, so I have good genes on my side. But I find it quite tiresome that we have to keep talking about sizes and how much weight we can lose.

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.

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

I want more children but for the next three years I want to act.

I was so completely anxious before I had a child, but now my biggest worry is something happening to her, so anything other than that I can handle. That's not to say I'm calm, because that would be b****cks! I wish it were the case, but it's getting better as I get older.

And the most important thing - apart from telling a good, believable story, and being a true character - is to be someone the audience will care about, even if you're playing a murderer or rapist.

For me personally, everything is on a kiss.
