Prince Charles and Princess Diana sat down for an interview on the eve of their royal wedding in 1981. Years later, the former royal couple’s interview revealed shocking details about their conversation.

"Nine O’Clock News" broadcaster Angela Rippon and Andrew Gardner were the ones who interviewed the Prince and Princess of Wales. But before the cameras started rolling, Queen Elizabeth II’s former private secretary, Michael Shea, gave them a stern warning.

According to Rippon, Shea reminded her and Gardner about the questions that they could ask the royal couple. He also said that if they ask about Princess Diana’s wedding dress, he would stop the interview immediately.

Following the interview, Prince Charles asked Rippon and Gardner if they would like to have tea with them. When they reached the private apartment, Rippon noticed that Shea was no longer around so she informed Princess Diana of what happened before the interview.

“I thought, ‘Well, Michael Shea’s not here, it’s just the four of us,’ and I said to Diana: ‘Ma’am, you know during the interview I wasn’t able to ask you, your wedding dress, is it everything you’ve dreamed of?’ And she clasped her hands together and she said: ‘Oh Angela, I had my last fitting just a few days ago in the workroom and when I put the dress on, all the girls in the workroom, they all applauded and a few cried and said, ‘Oh ma’am, you look just like a fairy princess,’” she said.

Meanwhile, Princess Diana’s interview wasn’t her only highly-publicized but an equally controversial conversation with an expert. Several years ago, the mom of two also sat down for an interview with Martin Bashir for Panorama.

The interview was released in 1995, and Princess Diana shared shocking information about the Royal Family. She also told Bashir that there was three of them in her marriage to Prince Charles and the statement was meant to be a shade to Camilla Parker Bowles.
