For me, the show must go on - it doesn't matter how ill you are, you get on and do it.

I love nice things - I consider Ralph Lauren sheets to be a necessity, not a luxury - but I've known what it's like to be poor.

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.

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 run or walk three times a week. I do Pilates, too, which is amazing - it makes you longer and leaner.

Any actress will tell you, when you've been given a starring role in the initial run of a show, you want to be getting the standing ovations every night, not just on review night.

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.
