You should make an effort on stage because it's a performance. The stage should be glittery and camp, but I don't go down the shops in full stage gear.

Someone had my number and they started text-stalking me. I've never replied to them. It was tempting to write back, but I resisted.

I was an only child, but then my parents resettled with different partners, and I am now one of six.

Philately is normally a boys' hobby but for some reason it was in vogue at my junior school. Between the ages of eight and ten I collected avidly. I'd pore over my Stanley Gibbons book, obsessively checking my collection's value. I always hoped I'd stumble across a really valuable one, a Penny Black or an Inverted Jenny, but it wasn't to be.

I've got quite a curvy shape so I try to wear stuff that's tailored.

In terms of influence, my style icons have been a mixture of Julie Andrews and Olivia Newton-John. When I was little I used to watch 'Grease,' 'Mary Poppins' and 'The Sound of Music' a lot. If you put all those things together you do kind of get my outfits. A slightly tarty nanny in a second-hand outfit. That is pretty much what I wear.
