Kevin Costner had an ‘ugly’ feud with the royal family after Princess Diana’s death: They ‘turned on me’

Kevin Costner was at odds with the British royal family in the 1990s.

During his interview on “The Howard Stern Show” on Tuesday, the Oscar winner, 69, confirmed that a sequel to his hit 1992 film “The Bodyguard” with Whitney Houston was in the works with Princess Diana as his planned co-star.

However, Diana’s death in summer 1997 caused the project to be canceled — and Costner subsequently faced the wrath of the royals, who didn’t believe that the princess was willing to do a Hollywood movie.

“When Diana passed, about a year later it had leaked out that I was prepping ‘Bodyguard 2’ with her. And what happened was, the royal family kind of turned on me a little bit,” he recalled.

“Like, ‘No, that’s not true.’ And it got actually kind of ugly,” Costner continued. “And I let it go for a while. It just got uglier and uglier.”

The “Yellowstone” star said that he ended up reaching out to Sarah Ferguson, Duchess of York, who initially connected Costner with Diana, and asked for her help.
