Princess Diana once made Prince Charles laugh hysterically after their royal wedding.

In an unearthed clip, the Princess of Wales seemingly flirted with the camera while walking beside her husband. Princess Diana stares directly into the camera and smiles with her beautiful teeth showing. She also smizes at the camera.

Prince Charles couldn’t help but laugh after seeing what Princess Diana just did. The couple’s royal wedding in 1981 seemed like a very happy occasion. But this wasn’t entirely the case.

While speaking with Andrew Morton, Princess Diana said that she was aware Camilla Parker Bowles was the church even before she walked down the aisle. As such, she was looking around for the Duchess of York when she entered the church.

“I knew she was in there, of course. I looked for her… So, walking down the aisle, I spotted Camilla, pale gray, veiled pillbox hat, saw it all, her son Tom standing on a chair… To this day you know – vivid memory,” she said.

Morton shared details about her conversation with Princess Diana in the book “Diana: Her True Story – In Her Own Words.” The book was released shortly after Princess Diana’s death.

Meanwhile, Prince Charles also made a confession to his friends just hours before he married Princess Diana. In the Channel 5 documentary “Charles and Di: The Truth Behind Their Wedding,” it was revealed that the heir to the throne became concerned over the fact that Princess Diana was merely just a child back then.

“She is exquisitely pretty, a perfect poppy, but she is a child. She does not look old enough to be out of school, much less married,” Prince Charles reportedly said.

And according to royal author Ingrid Seward, Prince Charles’ friends thought at that moment that the future King’s marriage to Princess Diana would be a disaster. And as it turned out, Prince Charles’ friends were right.
