Kevin Costner once confirmed a major rumor about Princess Diana that caused the Royal Family to turn against him

Kevin Costner once revealed that Princess Diana was being considered for a role alongside him in The Bodyguard 2 before her tragic death in 1997. According to him, plans were quietly in development, but after her passing, news of the project leaked—prompting the British Royal Family to deny the story and distance themselves from him.

Costner said the situation became tense and “ugly,” as the Palace pushed back against claims that Diana had been interested in acting. He eventually reached out to Sarah Ferguson for advice, who initially told him to let it go. However, he chose to speak up and insisted the story was true, even warning he would publicly defend himself if needed.

He also shared that Diana had been enthusiastic about the project and even discussed the possibility of a romantic scene. Years later, Prince William confirmed a personal detail to Costner, telling him that his mother had a crush on him.
