Princess Diana was friends with Princess Margaret’s daughter Lady Sarah Chatto even though the Princess of Wales had a fallout with Queen Elizabeth II’s younger sister.

Rebecca Perring, a journalist for Express, revealed that Lady Sarah and Princess Diana were so close to the point that the former invited the latter to her 1994 royal wedding. Prince Charles and Princess Diana attended Lady Sarah’s nuptials to Daniel Chatto separately. The month before the wedding, Prince Charles admitted to adultery.

Despite Princess Margaret’s alleged dislike of Princess Diana, Lady Sarah decided to stay friends with the mom of two. When Lady Sarah was 17 years old, she became one of Princess Diana’s bridesmaids at her wedding to Prince Charles in Westminster Abbey.

But following Princess Diana’s 1995 Panorama interview, Lady Sarah was left with no choice but to cut the Princess of Wales out of her life just like what Princess Margaret did.

In the BBC documentary “Princess Margaret: The Royal Rebel,” Craig Brown, the unauthorized biographer of the special, said, “She was always very, very cross with people like Diana and Fergie who got into scandals and so she would never have done a secret interview with Panorama or anything like that.”

Two years later, Princess Diana was interviewed by Andrew Morton for “Diana: Her True Story – In Her Own Words,” and she revealed that Princess Margaret wrote her a furious note of reproof.

But Princess Diana’s relationship with Princess Margaret wasn’t the only complicated one she had within the members of the royal family. According to Good Housekeeping, Her Majesty was also shocked to read the contents of Morton’s book that was released after Princess Diana’s death.

Princess Diana revealed that she reached out to the Queen in 1986 for help regarding her marriage, but the monarch appeared to be less sympathetic.

“I went to the top lady and said, ‘I don’t know what I should do.’ She said, ‘I don’t know what you should do.’ And that was it. That was ‘help,’” Princess Diana said.
