Sarah, whose title is Duchess of York (and who is popularly known as Fergie), appeared on The Kelly Clarkson Show following the release of her new novel, A Most Intriguing Lady.
She had both the host and actor Ike Barinholtz cracking up as she recalled her eventful hen party, the British equivalent of a bachelorette party, ahead of her 1986 royal wedding to Prince Andrew.
Ferguson, 63, said she and Princess Diana were dressed up in cop costumes for a night out at a club — and a photo showed the pair sporting uniforms with matching caps (and Diana in a pair of black frame glasses) with drinks on the table in front of them.
“We sat down, and the waiter came up to us and said, ‘Excuse me, this is a member’s club. And it’s for fun, and we don’t serve police officers here,’ ” she explained.
“They thought you were real police officers?” Clarkson asked, to which Sarah replied, “Yes!”
When they left the club, Princess Diana broke character when she saw a woman wearing a dress she had. Then, the pair were arrested for “impersonating police officers” and even put in the back of a police van. But when Princess Diana noticed “smoky bacon flavored crisps” in the van, she “started taking them and eating them.”
Sarah said, “The policeman in the front seat — ‘You can’t do that!’ “
Although the women turned their engagement rings from view in the police van, the cops eventually realized who they were.
Fergie said that she doesn’t miss Princess Diana, who died in a 1997 car crash, because “she’s with me all day.”
“She and I, laughed a lot. We got into trouble a lot,” Ferguson continued. “You know what she used to do? She used to tell me the worst story, joke story, just before I had to be serious.”
The Duchess previously said that she and Princess Diana, whom she affectionately called “Duch,” were best friends from the time they were teenagers, long before Diana married the then-Prince Charles and Sarah married his brother Prince Andrew. She recently said that Princess Diana would be “incredibly proud” of her five grandchildren from her sons, Prince William and Prince Harry.
