Camilla Parker Bowles reportedly didn't find Kate Middleton to be the perfect woman for Prince William in the beginning.

In Christopher Andersen's book "Game of Crowns: Elizabeth, Camilla, Kate and the Throne," the royal author wrote about the rift between the Duchess of Cornwall and Duchess of Cambridge. Camilla reportedly didn't like Middleton for the Duke of Cambridge and even asked Prince Charles to advise his son to split from her.

According to Nicole Stinson, a journalist for Express, the book also detailed Camilla's perspective about Middleton. Camilla reportedly found Middleton "pretty, but rather dim" and "too lowly" to marry a royal.

When Prince William and Middleton split in 2007 after six years of dating, the duchess was reportedly happy and deemed their separation as "wise." Unfortunately for her, the Duke and Duchess of Cambridge only separated for a few months and later got back together.

"I think I at the time wasn't very happy about it, but actually it made me a stronger person," Middleton previously said about their short split. "You find out things about yourself that maybe you hadn't realised. Or I think you can get quite consumed by a relationship when you are younger."

The book claimed that Camilla's disapproval of Middleton was due to jealousy because the latter was more popular than her. Middleton is well-loved by the public. In fact, some want Prince William and Middleton to take over the monarchy after Queen Elizabeth II and skip her and Prince Charles.

In 2017, a poll from YouGov revealed that 56 percent of the Brits favored the Duke of Cambridge to be the next king over the Prince of Wales. In addition, Middleton was leading the race to be the next queen with 63 percent rooting for her for the position. Only 8 percent wanted Camilla and 3 percent voted for Meghan Markle.

At the moment, the two duchesses appear to be amicable with each other. Prince Charles and Camilla also have nothing to worry about as the poll won't dictate the next heir. In addition, Prince William has already said that he has no desire to be king before his father.

"Although, like his father, William will be destined to have a far shorter reign than his grandmother, he has said he has no desire to 'climb the ladder of kingship' before his time," Gill Knappett said.
