Bomb disposal charity worker Camilla is said to have enjoyed a brief romance with the Prince in 2014.
The pair were spotted kissing in a London nightclub, but it turns out she's not the only Love Island star who has been linked to the royal.
Love Island host Caroline Flack is also rumoured to have dated Prince Harry in 2009.
Speaking before entering the villa, Camilla admitted: "It’s a small world. I hope it’s not weird. I’m excited to meet Caroline, she’s a great role model.
“I don’t know if she would want to talk about it though. I’ll cross that bridge when I come to it.”
In tonight's Love Island episode, Camilla is questioned about her time with the Prince by her fellow contestants.
But she gives NOTHING away.
In a game of truth or dare, Camilla asks for a truth.
“I’ve got a question,” Sam waves, “Is it true that you used to date Prince Harry?”
The rest of the Islanders are shocked at Sam’s question. “As in THE Prince?” a baffled Chris asks.
Camilla has a gulp of wine. “Honestly, a lady never tells.”
Meanwhile, the game moves on and Mike has to snog the girl he would choose in the recoupling and so he kisses Olivia.
Later in the Beach Hut, Montana says of the game: “It’s a chance to get the dirt that everyone wants to know and it also gives people an opportunity to just kiss who the hell they want!”
Chloe is dared to kiss the girl she most fancies – and she chooses Amber.
Love Island 2017 airs tonight at 9PM on ITV2.
