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.

It got to the point where most of my time went toward writing novels. I would still occasionally write short stories, but only when I was commissioned by an editor to write for a themed anthology or special issue.

The importance of heart health became very real for me when my father died of heart disease seven years ago. Having experienced the loss first hand, I am inspired to do everything I can to break the cycle and prevent families from losing loved ones to this preventable disease.
