Dance never really goes away; it just reforms and reinvents, and it’s become more athletic with new connection to fitness and sport. Dance used to have this exclusivity, but not any more.

I’d got a part in the original cast of ‘Cats’ when I was 16, and that kept me going for a while. After that, I felt lost, both personally and professionally – I was trying...

I love Monet: his ‘Water Lilies’ would look great on my wall. But would I prefer to see money helping kids get better from cancer rather than spending it on a work of art for...

It’s been said of me that I must get out of bed every morning and go cartwheeling down the road. Of course it’s not true. There certainly was a time in my 20s when I...

I’m a deeply boring person in real life; I don’t do any drinking and going out until four in the morning. I’ll usually head straight home for a cup of tea.

For years I used to try to straighten my hair, but I’ve reached a stage where I think, ‘I’ve got red curly hair, and it’s actually really great.’

I am probably more critical of myself than anyone else, I am very tiny – 5’1 and a half inches – so there’s nowhere for weight to hide.

As a dancer I’ve always checked my body constantly; ‘Am I having a good day or am I having a fat day?’

I used to hate my bottom because as a dancer, you’re supposed to have nothing there.

I just have to express myself somehow, either through singing, dance or fitness. You get sick of it; you have days where you think you don’t want to do it, but generally after I’ve done...

I was the shyest kid. I’d never speak, only if I had to. Honestly.

I’m the fussiest eater on earth; my husband despairs. I like chicken and pasta, and can’t resist milk chocolate. I figure if you’re going to do something naughty, make it really enjoyable.

It’s difficult to be a mother and maintain a career as a performer – but then it’s difficult in any industry.

I go to the gym regularly, not just for the way I look but because it makes me less cranky, too.

The pushy showbiz kid thing was always the performance, not the person. I’m very solitary. I don’t like socialising.

I see wrinkles and lines, and wear glasses to read, which I hate. But I am in a better place in my body than I used to be.

As a dancer, I’ve always checked my body constantly: ‘Am I having a good day, or am I having a fat day?’ I am probably more critical of myself than anyone else. I am very...

I’d never gone as a kid to an ice rink. There was always that fear that I’d break my leg and it would affect my career.

‘Dr Who’ is an extraordinary association that I have because I didn’t realise until I was in the show quite how worldwide it is and how popular and how dear it is to so many...

Looking in the mirror is very strange; we see only what we choose to see, good or bad.

I don’t read reviews, and I try not to read articles about me. It taints your outlook: if you believe the good things, you’ve got to believe the bad things, too.
