It all started when Lisa Snowdon mentioned she knew Hollywood actor Matt Damon via his wife Luciana, who she became close to while dating George Clooney.
Lisa had been encouraging her campers to deal with their hunger by pretending they were getting ready for a movie role, like Matt Damon may do.
"Imagine we're in a movie where we have to lose weight, like Matt Damon," said Lisa. "He's always having to do extreme stuff. He's a friend of mine and Lucy and the kids are eating.,.."
When pressed for more info, Lisa said: "I'm really good friends [with him]. He came to my birthday party. He's lovely. I got close to his wife when I was dating somebody else. He's a good dude. We've stayed with him and stuff. He's lovely."
Wayne Bridge then questioned Matt's height (Why? We don't know!). Lisa replied: "Short of six foot I would say, but when he's in extreme diet mode, his willpower is insane. [I am] trying to channel that kind of stuff."
Former footballer Wayne then came out with his own celebrity encounter, detailing how he'd met Mike Tyson in Las Vegas.
"I paid for my friends to go to Vegas and they took me to see him and get a thing signed," he said. "I remember they said, 'This is our friend Wayne.' And he was going, 'Bridgey, Bridgey, Bridgey!' It was f**king weird mate, honestly, so weird."
Diversity's Jordan Banjo said he'd met the Queen and Prince Harry (although did check he'd got the latter correct: "He's the ginger one, right? The nicest guy ever.")
Team GB Olympian Sam Quek said she'd played hockey with Kate Middleton and met Princes Harry and William, while actor Larry Lamb once filmed a movie with Bob Dylan!
"The movie never really went anywhere," said Larry. "He was playing an old rock 'n' roller coming out of retirement and I was playing his manager."
Martin Roberts, meanwhile, said he'd heard Hollywood actors Mark Wahlberg and Daniel Craig were both fans of his Homes Under The Hammer show.
Jordan then summed it up quite nicely by saying: "Hearing everyone's stories, it just shows even though we're on a show called I'm A Celebrity, a group of celebrities are still starstruck by other celebrities."
Former Britain's Next Top Model host Lisa was eliminated on Sunday night.
I'm A Celebrity continues at 9pm on ITV.
