There was a great strain in our family because my father didn't want anything to do with me. He was happy to see my brother and sister, but not me. I don't know why. Maybe it was shame. I don't know. But he never wanted anything to do with me. That rejection was terribly hurtful and it went on for years.

My father was having an affair with a 16-year-old when Mum was pregnant with me. She found out when I was three weeks old and left, not surprisingly.

My bottom is so big it's got its own gravitational field.

All I wanted to do was put together one of the best home maths systems in the world, and that's what we've done. I've loved numbers since I was two or three, and I get really excited about them. Now, I'm allowing myself to get excited about things. If you're doing it for a TV network or any major corporation, you have to put a lid on it a little.

Change is one of my favourite words.

I'm a bit frightened of the idea of a full facelift because, when you look in the mirror, you want to look like yourself.

I do need my independence. I have to have that.
