Princess Diana used to be a shy, young woman who rushed into marrying the future King, Prince Charles.

At the beginning of their relationship, Princess Diana was reportedly intimidated by Prince Charles. But it didn’t take the late royal very long to overshadow the Prince of Wales.

On the “Fatal Voyage” podcast, royal author Tina Brown shared details from her first meeting with Prince William and Prince Harry’s mom.

“I first met her face to face in November 1981. It was a few months after her wedding… She was a fresh, young newlywed and it was at the American Embassy at a dinner party… What really struck me was just how incredibly young and shy she was… She really was like almost like a schoolgirl… She blushed and she smiled and she made very charming small talk,” she said.

But after learning about the ins and outs of the palace, Princess Diana developed a sense of confidence that no one has seen from her before. She started involving herself in causes that were close to her heart, and she excelled at them.

However, no one was aware that while she looked happy on the outside, she was actually struggling from the inside. Princess Diana knew that Prince Charles was having an affair with Camilla Parker Bowles even before she married the future King.

According to Cheat Sheet, after Princess Diana gave birth to her two sons, she felt that she had already fulfilled her duty to Prince Charles. The latter was accused of marrying Princess Diana so that she could give him heirs, and that’s exactly what she did.

Shortly after Prince William and Prince Harry were born, Prince Charles and Princess Diana’s marital problems worsened. Fifteen years after they tied the knot, the couple announced their separation in 1992. Four years later, their divorce was finalized.

Princess Diana passed away less than a year later after her divorce.
