In his bookRebel Prince: The Power, Passion and Defiance of Prince Charles, Tom Bower wrote that the Queen even didn't want to meet or speak with the Duchess of Cornwall.
The unauthorised biographer of the Prince of Wales wrote that the future king had approached his mother one night with a request to end her fury with Camilla.
However, her Majesty was several martinis down at the time and made several biting comments about her son's lover - who was previously married to Andrew Parker Bowles.
According to Bower, the Queen called Camilla a "wicked woman" and said she wanted "nothing to do with her."
Royal expert Penny Junor wrote in the Daily Mail in 2017: "The Queen had wanted her gone before Diana’s death and felt no differently after it."
Expressreported that the Prince of Wales didn't introduce Camilla to the public as his girlfriend immediately after Princess Diana's death, despite her always being there for him.

However, it is commonly known that the Queen has been friends with Camilla over the years, and even recognised her in her speech for the Prince of Wales' 70th birthday.
Expressreported that the monarch allegedly never asked Prince Charles to break things off with Camilla because she has always made him happy.
When Charles and Camilla married in a civil ceremony at Windsor Guildhall in 2005, the Queen and her husband Prince Philip held a reception for the couple in Windsor Castle afterwards.

The publication also reported that the Princess of Wales never blamed Camilla's relationship with Prince Charles for her failed marriage.
Dr Lily Hua YU, an acupuncturist and herbalist for Lady Diana Spencer told the Daily Mail that the divorcee blamed her failed marriage on the fact she had a terrible relationship with her mother.
"She told me she did not like her mother and thought she was an alcoholic," she claimed.
"She felt she had no one to guide her when dealing with complicated situations, and if she’d had a good mother she would have had a successful marriage."
