Sinitta has been telling fellow I'm A Celebrity campers about her love life - including her relationships with Simon Cowell and Brad Pitt.
The ex-chart star, who dated both men in the 1980s before they found fame, said Brad looked "hot" when he was naked.
The So Macho singer said she was far more famous than both her exes at the time they were dating.
However she was coy about revealing too much.
Asked who was the better lover, she was non-committal and responded: "Who do you think?"
Sinitta said of Brad: "He was beautiful with the most amazing body. I saw him for two years."
She went on: "He was fun, he was young and very sweet. Some ardent fan gave me a slap when I came out of a supermarket over that relationship!
"It was before he made Thelma And Louise but even I saw that movie and thought 'Oh my God, what have I done?'."
Chatting to fellow campers in the Australian jungle, including model Emily Scott and McFly's Dougie Poynter, she batted away a question about the size of the Fight Club star's "manhood".
"Much bigger than yours, Dougie," she said.
