Princess Diana was allegedly arrested a week before Sarah Ferguson's wedding due to her bachelorette party antics.
The former Princess of Wales, who was a close friend of Prince Andrew's wife, was caught posing as a police officer the nights before Fergie walked down the aisle.
Prince Andrew and Fergie married in July 1986.
Speaking about the incident, Fergie told the White Wine Question Time podcast: “At my hen night we dressed up as policewomen and got arrested by the park police.”
“And they put us in the back of the park police van and Diana leaned over and ate her smoked bacon fries – the man who was driving. Then they arrested us and finally he had to move his ring, his call sign .And then, finally, we got off.”
The Duchess of York then explained Queen Elizabeth II's reaction to the situation, continuing: “Indeed, I was dragged to the boss the next day. But luckily, HM laughed.”
And he added: “We both showed our rings because I already had one, it was certainly a very good memory.”
