Princess Diana was devastated about the end of her marriage with Prince Charles, but didn’t realize she hurt her son, Prince William, by sharing details of her husband and Camilla Parker Bowles’ affair with the world.

When Diana sat down for her Panorama interview with Martin Bashir in 1995, her eldest son was furious and vowed to never forgive his mother for sharing their home life with strangers.

In the Amazon Prime documentary “William and Harry: Brothers in Arms,” royal correspondent Katie Nicholl recalled a conversation with Princess Diana’s friend, Simone Simmons, who revealed William reached out to his mother after the interview aired.

“William was exposed to everything from the interview and called his mother in a fury and a rage,” Nicholl said.

The young prince reportedly let his emotions get the best of him and lashed out at the princess of Wales. “[She told me] it was the one time William turned on his mother and said, that he would never forgive Diana for what she’d done.” the commentator recalled.

Although this happened when Prince William was young, years later in the BBC documentary “Diana, 7 Days,” William insisted he understood why his mother exposed details about Prince Charles and Camilla’s affair.

“I can understand – having sometimes been in those situations, you feel incredibly desperate and it is very unfair that things are being said that are untrue. The easiest thing to do is just to say or go to the media yourself. Open that door. [But] once you’ve opened it you can never close it again,” he said.

Prince Charles and Princess Diana finalized their divorce in 1996. The following year, the princess of Wales died in a car crash in Paris.
