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

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.

I don't want to fly the flag for being unhealthy and overweight, but I don't want to fly the flag for being too thin, either.

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.

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.

Adele is great because she promotes the idea of being happy as you are.

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.
