I realise having work done makes you look older - and everyone's starting to look the same, which is a problem. I've admitted that I had a cyst removed from my lip and had it filled - I had to; the lip was half gone. And I've tried Botox, but I don't do it any more. I'd tell anyone who's going to have it done not to do it.

I've made some stupid decisions, so I have to be careful. I once said 'no' to a film that was a number-one hit. And 'Date Movie' had the smallest budget of any movie I'd been in, and it went to the top of the box office.

People see me as a person who can make them some money, which makes it hard to make real friends. I'm asked to do a lot of stuff for free - to wear certain clothes, turn up to events - people use you to make money. I think that's why I tend to jump into relationships.

I write simply because I hear voices of people in my head who won't give me peace until I convey their stories to the rest of the world. Seriously. They've always been with me. While other girls played with dolls, and my brothers with Hot Wheels, I was busy traveling through space or traipsing through graveyards with my imaginary playmates.

My mum and dad ran a family cafe in Sligo for 35 years and worked long hours. We grew up in a very hard-working family and had a lovely atmosphere, as we lived above the restaurant. It definitely made me want to work hard, whatever I chose to do. As the baby of seven kids, I was definitely a bit spoilt.
