Queen Camilla's 'Instinct': Consort 'Took All the Nastiness From Princess Diana Separation' to Better Understand 'What King Charles Needs'

King Charles III and Queen Camilla celebrated their 19th wedding anniversary on April 9, but the royal marriage at one time was unthinkable even after Diana, Princess of Wales' death in 1997.

"The fact that she could take all the nastiness when they [she and Charles] separated from Diana, that now she knows exactly what King Charles needs," royal expert Angela Levin shared.

"I wrote her [Camilla's] biography and she's got this very strong instinct of knowing what is right at the right moment," she added. "She's been there so solidly with the work and the engagements, when you saw the picture of their 19th wedding anniversary that came out yesterday, you can see that they are so interactive together. I think that feeling [that] you are loved is just as important as having a pill."

Her Majesty has been hailed as "remarkable" as the royal consort wins praise for stepping up for the monarchy during King Charles III and Kate, Princess of Wales' cancer battles. This led royal expert Charles Rae to state that Her Majesty is: "One of the best things to happen to the royal family in years."

Even with the Queen's praise spreading far and wide, many cannot forget the pain she caused the King's first wife.

The now Queen began having an affair with the then-Prince Charles in the mid-1980s, at a time when both were married to Andrew Parker-Bowles and Diana, Princess of Wales, respectively. This was a resumption of their relationship that began in the early 1970s but ended once Camilla decided to marry Andrew. Their romance would eventually surface in the early '90s, when "Camillagate" made the headlines and kicked off the "War of the Waleses" between Charles and Diana.

Andrew and Camilla divorced in 1995, and the Prince and Princess of Wales followed suit in 1996. After Diana's tragic death, any plans to slowly introduce Camilla to the British public were immediately halted and remained that way for two years. The couple appeared together in public for the first time in 1999, but it would be another six years before any talk of marriage became viable.

The King and Queen have won the hearts of many, but numerous people still praise the late Princess of Wales despite the large amount of time that has passed since that tragic, late summer day in 1997.

"As we rapidly approach 27 years since she died, future generations will never forget her thanks to her [sons] Princes William and Harry," a former palace aide who worked with Diana in the early 1990s spilled. "Even though both have taken very different paths in life, their love and passion for their iconic mother lives on through their loving words about her. I doubt anyone will still be discussing Charles and Camilla 30 years from now."
