Queen Camilla was reportedly displeased with Prince Harry's portrayal of her in his memoir, "Spare," according to royal expert Nick Bullen. The co-founder of True Royalty TV shared insights with Fox News Digital about Queen Camilla's alleged reaction just days before her and Prince Harry's expected reunion at King Charles' coronation.

Bullen stated, "I know from various people who are close to her [that] she was pretty furious with what was being said about her." However, he also mentioned that Camilla isn't someone who would confront Harry or Meghan Markle over the issue, adding, "She just moves on."

Although Camilla may not forgive or forget Prince Harry's words, Bullen said she doesn't dwell on the situation: "She plays a much longer game, and she plays with a much straighter bat. She was, I'm told, annoyed by what was said but moved on pretty quickly from what was said."

In "Spare," released in January, Prince Harry revealed shocking details about his relationships with his father, King Charles, and brother, Prince William. He also accused Camilla of being a "villain" and the "third person in their [King Charles and Princess Diana] marriage." The Duke of Sussex called her "dangerous," alleging that she had connections to the British press and had "sacrificed me on her personal PR altar."

Prince Harry's biographer, Angela Levin, author of "Harry: A Biography of a Prince," disagreed with his portrayal of Camilla, stating, "She's not a villain."

Levin, who also wrote "Camilla, Duchess of Cornwall: A Royal Survivor," argued that Camilla doesn't crave attention or the limelight and is content being in the background. She told Us Weekly, "Camilla is somebody who feels that, you know, give it time, and it'll all come round."

Queen Camilla's coronation will take place alongside King Charles at Westminster Abbey on Saturday. Prince Harry is expected to attend the ceremony, but reports suggest he will return to the U.S. immediately afterward.
