Princess Diana wanted a simple and normal life.

The late People's Princess won the hearts of the public when she married Prince Charles. In fact, she became one of the most talked and most photographed persons when she was still alive. However, she didn't like the spotlight and had always wanted to be "normal."

"I started off with a brief to look after William and Harry," Khen Wharfe told Yahoo News' "Royal Box" (via Express). "They're no different from any other child. Diana was always keen to bring some normality. One of her famous catch phrases was 'I want to be normal.'"

Unfortunately, Prince Diana didn't get what she wanted. According to Wharfe, being part of the royal family was like "a piece of theatre." The late Princess of Wales was obliged to put up a "performance" for the press.

"Well it isn't normal to have X number of shifts, it isn't normal to have access to more than one palace to have these luxury holidays, specialised travel and a helicopter land in your backyard," Wharfe explained. "Being in the royal family is a piece of theatre, this is unreal - you are performing."

At one point, Princess Diana upstaged Prince Charles. According to Lady Elizabeth Anson, a party planner and cousin to the Queen, the Prince of Wales realized this when they received visitors who wish to see Princess Diana and not him.

"[Diana] sort of metamorphosed into a very, very elegant blonde beauty. They did a visit to Wales which was the beginning of, for Prince Charles, realizing, 'They've come out to see my wife, they haven't come out to see me,'" Anson told People.

In related news, Princess Diana revealed in the past interview that Prince Philip advised Prince Charles to get back to Camilla Parker Bowles if their marriage doesn't work after five years. According to Prince William and Prince Harry's mom, she already had an idea but only confirmed everything when they split.

"My father-in-law said to my husband, 'If your marriage doesn't work out, you can always go back to her after five years,'" Princess Diana said in a 2017 Channel 4 special that utilized taped conversations between the Princess of Wales and her voice coach. "Which is exactly—I mean, for real I knew that it had happened after five—I knew something was happening before that but the fifth year I had confirmation."
