I do worry about my looks being shot in high definition on the Roadshow. Whoever invented that must have been a bloke, and he was probably about 18 years old. It's a nightmare. I get followed round by a make-up artist to ensure I look half-decent. That has been a slight wake-up call.

I work in a visual medium and I am judged by my appearance. There's going to come a time when my face won't fit any more, for whatever reason. When I got the job of presenter on the Six, other people were being fired. I got taken in one door and I was hired. Other presenters were going out of the other door. I just thought, 'That's how it will be for me one day. I'll be the last person to find out about it and, when it does happen, don't get bitter and twisted about it'.
