Meghan Markle left Queen Elizabeth II infuriated after snubbing the monarch's advice.

A bombshell new book recently disclosed a shocking part of Meghan and Queen Elizabeth II's relationship. While it looked like they had a great connection before the Megxit happened, the book revealed that the Duchess of Sussex, instead, annoyed the queen one time.

British journalist Tom Bower released "Revenge: Meghan, Harry And The War Between The Windsors," in which he divulged that Her Majesty and Prince Charles held a conference call after the Sussexes' marriage.

The central members of the royal family were reportedly trying to mend the messy dispute Meghan has with her father, Thomas Markle.

However, Meghan did not follow them at all and said it was unrealistic to think she could fly to Mexico.

According to Bower, the 77-year-old patriarch said he was embarrassed about staging paparazzi photos. Thomas infamously criticized the royal family in several interviews, as well, as he had no way of connecting to his daughter.

In the end, he also alleged that he feared he would die without speaking to her again.

The book came out months after Thomas was rushed to a hospital after a major stroke. The health issue caused him to lose his ability to speak, but it did not affect his life as a whole.

In the same book, Bower added that Prince Harry's friends from Eton College said that the Duke of Sussex was "f- -king nuts" for dating Meghan after she berated them for their "jokes about sexism, feminism and transgender people."

"Without hesitation, Meghan challenged every guest whose conversation contravened her values. According to Harry's friends, again and again she reprimanded them about the slightest inappropriate nuance. Nobody was ­exempt," the book claims, per New York Post.

But recently, royal author Duncan Larcombe claimed that Prince Harry was already regretting the decision he knew he should have never made.

In an interview with Closer Magazine (via Express UK), Larcombe noted that the royal prince looked homesick.

"Harry's suddenly playing polo again and drinking with his new friends - all things he used to enjoy doing in the UK. Meghan is cheering him on on the sidelines, helping create this perfect LA life for him to justify what he's given up in the UK," he went on.
