Princess Diana had a crush on the bodyguard.

Not her own bodyguard, of course, but Prince William recently shared an eyebrow-raising revelation to Kevin Costner—noting his late mother used to be starry-eyed for him. 

“I happened to be in England, and I got this message that the prince would love to talk, and I said, ‘What?’” Kevin explained in an interview with People published June 18. “We met in this room, and it was just us. He walked up, and we shook hands. The first line out of his mouth was, ‘You know, my mom kind of fancied you.’"

And while Kevin, who noted that William was “quite the young man” during their conversation, was surprised to hear of Diana’s affections, he did know her fairly well. After all, the duo—introduced by Duchess of York Sarah Ferguson—were planning to collaborate on a sequel to The Bodyguard. 

“There was a moment that that was really flying down the tracks,” Kevin noted of the Whitney Houston film sequel that never was. “Very quietly, because it's how I operate.”
