The members of the royal family sometimes argue with each other.

Queen Elizabeth II, Prince Charles, Camilla Parker Bowles and Princess Diana were embroiled in a feud due to the Prince of Wales and Duchess of Cornwall’s affair. Recent reports claim that Prince William and Prince Harry are feuding, too.

Here’s a list of the most shocking royal family feuds in history according to Us Weekly.

Queen Elizabeth II and Camilla

Initially, Queen Elizabeth II didn’t support Prince Charles’ relationship with Camilla. In fact, the monarch was too cold to Camilla that Prince Charles had to request his mom to warm up to his girlfriend.

However, according to Tom Bower in his book “Rebel Prince: The Power, Passion and Defiance of Prince Charles,” the Queen was furious when the heir approached her. At the time, she was drinking several martinis and called Camilla a “wicked woman.” Her Majesty also reportedly said that she wanted nothing to do with the duchess.

Princess Diana and Camilla

Prior to being rivals, Princess Diana and Camilla were actually friends. However, when the late Princess of Wales realized that the future king and Camilla had an affair, the relationship of the two women was strained.

In fact, Princess Diana confronted Camilla about her and Prince Charles’ affair one time. During their argument, Prince William and Prince Harry’s mom said, “I know what's going on between you and Charles and I just want you to know that.”

The Prince and Princess of Wales’ marital woes reportedly prompted Prince Charles to desperately get out of their marriage. Meanwhile, Princess Diana was too hurt by her husband’s infidelity that she made a secret interview where she said that their relationship didn’t work because “there were three of us in this marriage” implying about Prince Charles and Camilla’s affair.

Prince William and Prince Harry

A few weeks ago, the Duke and Duchess of Sussex announced that they are officially splitting their household from the Duke and Duchess of Sussex. Prior to that, there were rumors that there was a falling-out between Prince Charles and Princess Diana’s sons.

On Sunday, the two princes were seen together. According to a body language expert, Prince Harry was anxious and was “desperate to avoid” Prince William.
