After the 2012 Olympics I hosted the parade. I had on a little skirt and when the prime minister came on everyone cheered. I thought: “Oh my God, they love David Cameron,” but they were cheering because my skirt had blown up, and I’d flashed my knickers at him.

A hairdresser through the week and a star on the weekends.
