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.

The scariest time of my life was when I knew my Nana was dying. It was horrible, as there's nothing I could do to stop it. I grew up living with my Mum, brother and Nana (my mum's mum), so it felt like I lost a parent rather than a grandparent. It makes you realise the fragility of life.

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 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.

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.

No woman is completely happy with their body.

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.
