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.

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

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 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.

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.

The most annoying thing I found was all the people pretending to be me on MySpace and Facebook. I'm not a member of either, but apparently there is an 'official' Nikki Sanderson MySpace page, complete with rants about how terrible identity fraud is, which is ironic.

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