The veteran star admits his fears were only alleviated once he realised how uncomfortable it is to dress as a female.
He says, "I tell you what, I'd never dressed as a woman (before), honestly. I'm putting on these tights and bra, and everything, and I was thinking to myself, 'Suppose I like this.' I got very, very nervous. I've got the tights and some knickers on and I'm going, 'Wait a minute!'
"Fortunately for me, it turned out to be extraordinarily uncomfortable, because if you're a man you've got to wear hips. They give you hip pads and bosoms and everything and it's like living in equipment. It's like you're going skiing, but there's no snow."
