I've been told if you're an actress you can't sing, if you're a dancer you can't act, you can't do theatre and be respected if you've done a TV soap, you can't have a No. 1 record. All these different things they've told me I can't do, but I wanted to do them, so I've done them.

A huge part of youth is how you behave: I'm always looking for fun and anything that makes me feel alive - that in itself keeps me feeling young.

Any actress will tell you - it's really hard. If you're not an A-list Hollywood movie star, if you're in the middle, there are people who assume you wouldn't do certain things without even asking you, when actually you probably would. And there are people who always think you are busy doing something else.

It's taken a while, but I've finally grown up and got my head around the fact that the healthier the food you eat is and the more exercise you do, the lighter you'll be. It really is that simple.

I think you have to be careful not to do too much as yourself. Otherwise you stop getting the acting roles, and at the end of the day that's what I love.

There are times when I'm so bored with being healthy and organic that I crave sugar and additives.

I look very different on camera compared with how I do in real life. On camera, I look my best when everything is enhanced, especially my eyes - I like a smoky eye. In real life, I like myself best in tinted moisturiser, lip balm and mascara.
