Before Kate Middleton and Meghan Markle, the royal sisters-in-law who everyone talked about were Princess Diana and Sarah “Fergie” Ferguson.

Diana and Prince Charles tied the knot in 1981 and Fergie married his brother, Prince Andrew, five years later but the two women knew each other before they joined the royal family. In fact, it was the Princess of Wales who set Fergie and Prince Andrew up.

Diana recommended Ferguson to Queen Elizabeth II, who invited her to a “dine and sleep event at Windsor Castle during Ascot week.” At dinner, Ferguson was seated next to Andrew and that’s when they began having a romantic relationship.

While married to the princes the women shared a bond few could understand, but after their marriages ended so did their friendship for a reason Ferguson couldn’t understand. Here’s why Diana really stopped talking to Fergie and if she was attempting to reach out to the duchess before her tragic.

Why Princess Diana stopped speaking Ferguson

After they separated from their husbands in 1992, the ladies were closer than ever. They would go out for lunches often and vacationed together with their children. But in 1996 that all changed.

Diana stopped speaking to Ferguson and sources close to the princess insisted that it was because Diana was upset over some things Fergie wrote in her autobiography.

“I really miss Diana. I loved her so much,” Ferguson previously told Harper’s Bazaar. “Diana was one of the quickest wits I knew; nobody made me laugh like her. But because we were like siblings–actually, we were fourth cousins and our mothers, who went to school together, were also best friends–we rowed.”

Diana was going to contact Fergie just before she died

Despite their falling out, Fergie always believed that Diana wanted to make amends with her but died before she could do so. The duchess later received confirmation of this from a mutual friend.

Ferguson explained that she found out her former sister-in-law was going to contact her just before her tragic death. The friend informed the Duchess of York that Diana had been looking for her and wanted to connect.

“The saddest thing, at the end, we hadn’t spoken for a year, though I never knew the reason, except that once Diana got something in her head,” Ferguson said. “I tried, wrote letters, thinking whatever happened didn’t matter, let’s sort it out. And I knew she’d come back. In fact, the day before she died she rang a friend of mine and said, ‘Where’s that Red? I want to talk to her.’”

Unfortunately, the princess and Fergie never got that chance to reconnect. Diana died on Aug. 31, 1997, following a car crash in the Pont de l’Alma tunnel in Paris.
