Queen Elizabeth II was mad at Sarah Ferguson following her split from Prince Andrew.

The Queen and Duchess of York have a lot in common, so they get along well together. Ferguson even admitted in one interview that she called Queen Elizabeth II “mama.” However, they had a falling-out.

In the 2019 documentary “Royals at War,” the two women’s relationship was reportedly strained when the Duke and Duchess of York parted ways. Her Majesty felt bad after Ferguson initiated the breakup.

“The Duchess was in apparently care-free mood as she collected Princess Beatrice from school just at the moment the official statement was being handed out by the Palace,” the documentary revealed.

“The announcement made it plain that she initiated the separation,” the narrator continued. “As the day went on it became clear the Queen was not only saddened by the break-up of the marriage, she was also angry at the way the Duchess handled the issue.”

Ferguson confessed in her autobiography how Queen Elizabeth II encouraged her “to reconsider, to be strong and go forward.”

However, she didn’t listen to her mother-in-law’s advice. Instead, she was embroiled in a controversy when she was photographed with her financial advisor John Bryan who appeared to be kissing and sucking her toes. Royal experts believed that it was the last straw that led to her divorce.

Ferguson was criticized for the shocking scandal. According to royal commentator Dickie Arbiter on ITV's “The Royal Wives of Windsor,” one didn’t expect somebody to crawl through the bushes to take photographs. However, in the same token, a married woman isn’t expected to go away with somebody not her husband and sunbathe topless.

Ferguson has slowly made her way back into the royal fold and her relationship with Queen Elizabeth II has since improved. Her Majesty is reportedly still a huge fan of Prince Andrew’s ex-wife and has an “enormous affection” to her former daughter-in-law. So chances are high that Ferguson will return to the royal fold. In fact, royal author Anna Pasternak said that royal fans can expect to see a lot more of Ferguson within the inner sanctum of the royal family.
