Never say never - you don't know what's going to happen in the future.

No woman is completely happy with their body.

I once had a letter from a man who asked to do something very weird. He told me he wanted to sit on my shoulders and for me to then walk around his town to raise money for charity. He described himself as being 6ft and I was thinking, 'I'm only 5ft 4in, and you want to sit on my shoulders?' How bizarre.

Taking part on this show is a million miles away from my normal acting jobs.

I was quite into biology and chemistry at school, and I did well in my maths GCSE – I really liked it and got an A – so I quite fancied a career in forensics or something like that. But I bet if you put a maths exam paper in front of me now I wouldn’t have a clue.

I know parts of all the decades come in and out of fashion, but you never get to wear an entire outfit exactly how it was.

I'm not very firey, but when I go, I go. I don't shout, I just get upset.

I get really irritated with crap drivers, so the last time I got cross was probably behind the wheel. I'll shout from the safety of my car, with the window up, but if anyone ever got out and challenged me I'd be terrified.

I have body hang-ups - but I work the best of what I've got.

Since being 17, I can honestly say I've only been ill twice on drink. I stop when I feel happy, so I don't throw up.

If I see someone I'm in awe of I'm like, 'Oh my God. Oh. My. God.' But on the outside I'm very calm. I'd never run up and hassle anyone.

People are mostly very nice, and I always say hello. I'm laid back, so I don't mind. I think if people watch the show and want to say hi, you've got to be nice.

The most wonderful person I met was John Travolta. He's one of the ultimate movie stars of all time.
