Working for Sarah Ferguson was “absolutely chaotic,” claims author Andrew Lownie.

One reason chaos ensued was due to the former Duchess’ capricious nature.

“She couldn’t make up her mind,” the author of “Entitled: The Rise and Fall of the House of York,” told Page Six in a recent exclusive interview. “She changed her mind at the last minute.”

Lownie claims that staff morale was terrible, with people weeping in bathrooms and quitting after working there for “half a day. “Very few people stayed, and if they did, “it was a sort of 24-hour-a-day job because she has this extraordinary energy and she would be flying off in different places, not very organized.”

Ferguson was also allegedly known for wasting food.

“Various meals being prepared and then actually not having any of them,” Lownie says, like having a chef prepare a meal and then deciding at the last minute to go out to eat.

“Huge waste,” he emphasized. “It’s extraordinary…everything has to be new…Just this Marie Antoinette kind of life, you know, easy come, easy go.”

Ferguson, the former Duchess of York, 66, was married to the former Prince Andrew and shares two daughters with him, Princess Beatrice and Princess Eugenie.

Her life has been in turmoil since she and her ex were stripped of their royal titles and then forced to move out of their longtime home, Royal Lodge. Despite divorcing in 1996 after ten years of marriage, the couple famously lived in the same mansion, with Ferguson constantly parroting that they were the “happiest divorced couple in the world.”

In February, things got even darker when the former Prince, now known as Andrew Mountbatten-Windsor, was arrested on his 66th birthday on suspicion of misconduct in public office for allegedly forwarding confidential trade documents to the late convicted pedophile Jeffrey Epstein.

If convicted, he could face a maximum sentence of life in prison.

There are also embarrassing emails that Ferguson sent to Epstein, in which she pleaded for money and referred to Epstein as a “legend” and quipped, “Just marry me.”

Lownie describes the former Weight Watchers spokesperson as “very manipulative,” who was constantly “playing off people against each other. These people kind of got dragged into her crazy schemes, designing a lingerie range, setting up an artist colony in the Bahamas.”

The author alleges that many of her business proposals were “about trying to fleece someone out of some money.”

Last month, Ferguson was spotted for the first time in months in the Swiss Alps, where she has been hiding out.

“Fergie has been keeping an incredibly low profile while high up in the Alps,” a source told The Sun. “The area is absolutely beautiful and it’s very quiet most of the time, so it’s the perfect place for a high-profile figure such as her to lie low when the heat is on.”

Page Six has reached out to Ferguson’s rep for comment, but didn’t immediately hear back.

It’s the first sighting of the former royal since Sept, 16, 2025, when she attended Katharine, the Duchess of Kent’s funeral held at London’s Westminster Cathedral.
