Diana, Princess of Wales was smuggled into a London pub disguised as Freddie Mercury's boyfriend by late comedian Kenny Everett

Kenny called up his friend, the late Queen frontman Freddie Mercury, and after Cleo put her brother's camouflage jacket on her and found out they were all going to the famed London gay bar, she jumped at the chance and got the 'We Will Rock You' hitmaker to put sunglasses on her to disguise her identity.

Cleo told the Daily Mirror newspaper: "Diana asked us where we were going and what we were wearing.

"My brother was a war photographer in El Salvador. He had given me his camouflage jacket. It looked great on her, so Kenny got out a leather cap, and she put that on, and then Freddie gave her aviator sunglasses.

"She said, 'I want to come too.' We thought she was joking.

"Kenny said, 'We are going to a place where there are big hairy men, and they fight.'

"He could just see the headlines - 'Future Queen of England Dies in Gay Bar Brawl.'

"But Freddie just said, 'Oh, let the girl have some fun.'

"We went to the Vauxhall Tavern. Diana just looked like Freddie's boyfriend, a male model, and she loved it."

They were there for "20 minutes" before Kenny, Freddie and Cleo ordered a cab to take the Princess of Wales back to her residence, Kensington Palace.

She continued: "They stayed 20 minutes. We got a cab to drop her off at Kensington Palace.

"I can transport myself back to that lunch and see Diana throwing her head back, laughing."

Kenny died from an AIDS-related illness on April 4 1995 at age 50, and Cleo fondly remembers how much fun it was to party with the star.

She added: "We would go to parties and literally swing off chandeliers.

"And when a party was boring, if there was Champagne, we would try to hang onto it and climb out of the window with it."
