It's been two decades since they were a couple, but Sinitta still holds a candle for Brad Pitt.

The 43-year-old singer -- who dated the father of six before he hit it big in the late '80s -- opened up about their relationship on England's I'm A Celebrity...Get Me Out Of Here! Wednesday.

"He was beautiful with the most amazing body. I saw him for two years," she told her castmates. "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!"

Once Pitt became a household name, Sinitta regretted splitting with the two-time Academy Award nominee (now 47).

"[The relationship] was before he made Thelma and Louise, but even I saw that movie and thought, 'Oh my God, what have I done?'"

A McFly band member named Dougie Poynter then asked about Pitt's "manhood," to which Sinitta cheekily replied: "Much bigger than yours, Dougie!"

Pitt isn't the only A-list star Sinitta has romanced: she's also been linked to Simon Cowell and musician David Essex.
