The 80-year-old star has recalled going to a sex bash in Paris back in the 1960s, but the 'Great British Bake Off' judge thought she was going to a normal party until she walked in and saw "room after room of bouncing bottoms everywhere".

She says: "I did go to an orgy in Paris, but I have to claim I didn’t know I was going to go to an orgy.

"I thought I was going to a party. Went with a very nice guy, so thought that would be great.

"All I can say is room after room of bouncing bottoms everywhere … on the floor, in all the rooms. I was so embarrassed."

Prue's pal suddenly "vanished" and she realised the only thing to do to become "invisible" was to strip naked herself.

Speaking on Saturday night's (24.04.21) 'The Jonathan Ross Show', she adds: "Anyhow, this guy, he thought it was fantastic.

"So he just vanished. So there I am, 19 or something.

"So I went to the bar and somebody immediately said to me, ‘Why have you got your clothes on?’ I said, ‘I’m just going to change.'

"I’d walk away. Someone else saying, ‘Why have you got clothes on?’

"So I realised the only way to be invisible was to take my clothes off. So I took my clothes off and walked around this party.

"Spent the next hour saying I was going to the bar, the loo, looking for a friend. I missed the orgy, although I was there."'The Jonathan Ross Show' airs on Saturday on ITV at 9.35pm.
