Prince Philip reportedly once called Sarah Ferguson's attention for being too friendly with the servants.

According to Anna Kretschmer, a journalist for Express, the Duke of Edinburgh once called the Duchess of York a "flirt" due to her flirtatious behavior. The claim was first made by biographer Allan Starkie, who shared an incident where Ferguson walked into a room to have dinner with Queen Elizabeth II and Prince Philip.

When Ferguson arrived, she greeted each servant with their first name. The duchess is popular for her bubbly disposition, which didn't sit well with Prince Philip who criticized it. "I thought you gave up flirting with the servants ages ago," the 97-year-old reportedly told Prince Andrew's ex-wife.

Prince Philip wasn't the only one who noticed Ferguson's flirtatious behavior. According to Fay James, the Duchess of York took her flirting "to a whole new level" when she was seen with Prince Albert of Monaco.

"She was hanging on his every word, using any and every excuse to touch his arm, laughing at everything he said – it was plain to everyone watching she was very taken with him," an eyewitness said. "She's already married one prince – it should come as no surprise to anyone that she’s openly flirting with another!"

Ferguson has been linked to a number of wealthy men. Aside from marrying the Duke of York, she dated Spanish businessman Manuel Fernandez. However, her biggest scandal involved her financial advisor, John Bryan, which many believed was the reason why she and Prince Andrew split.

"She was famously photographed with her financial advisor and she was wearing a bikini in some garden in the south of France and he appeared to be sucking her toes," royal biographer Penny Juror said in the documentary. "She was at Balmoral when those photographs came out. The family came down for breakfast and there was Fergie in this shocking scene and that was the end."

Prince Andrew and Ferguson remain friends following their divorce. The Queen and the Duchess of York are also able to maintain their relationship. In fact, they meet each other secretly and due to the monarch's sympathy, the duchess felt that Queen Elizabeth II is "secretly rooting for her."
