Queen’s frontman Freddie Mercury apparently snuck Princess Diana into a gay club in the 1980s after dressing her up in male drag, according to a memoir published in the Sunday Times of London.  

Mercury dressed Princess Di as a male model to get her into a high-profile London gay club and the beloved royal went unnoticed, according to "The Power of Positive Drinking," by comedian Cleo Rocos, the Huffington Post wrote.

Rocos dished about British TV star Kenny Everett and Mercury disguising the princess so she could be snuck into the Royal Vauxhall Tavern in south London.

Diana was able to enjoy a night out on the town without any attention thanks to an army jacket, black cap and dark sunglasses.

"When we walked in ... we felt she was obviously Princess Diana and would be discovered at any minute. But people just seemed to blank her. She sort of disappeared. But she loved it," Rocos says, adding that the club was packed, but the people were preoccupied with Mercury, Everett and herself being there so it was easy for the most famous young woman in the land to slip under the radar. Diana was even able to order a drink at the bar, but the group left after only 20 minutes.

"She did look like a beautiful young man," Rocos writes. "She was always a very fit girl, so they might have thought, 'There's a nice young man with pert buttocks.'"

The princess was considered a hero in the gay community in the '80s due to her visits to patients who were dying of AIDS in hospitals. She even shocked the world when cameras captured her holding hands with a person dying of AIDS.

The group was inspired to visit the gay bar after drinking champagne all day and watching "Golden Girls" reurns with the volume turned down, impersonating the character’s voices “but with a much naughtier storyline," Rocos writes, according to the Daily Beast.

When Diana asked about their plans for the evening, her friends told her about the gay nightclub outing.

Rocos, now 50, recalled: “Kenny said, ‘It’s not for you. It’s full of hairy gay men. Sometimes there are fights outside.’

“We pleaded, ‘What would be the headline if you were caught in a gay bar brawl?’

“But Diana was in full mischief mode. Freddie said, ‘Go on, let the girl have some fun’.

Diana wore what Everett picked out and the group hailed a cab.

Di reportedly had the clothes sent back with a note that read: “We must do it again!"

The outing that reportedly took place in 1988 happened around the same time Diana’s relationship with Prince Charles was on the rocks.

Freddie Mercury died of an AIDS-related illness at age 45 in 1991, and Everett from an AIDS-related illness at age 50 in 1995.

Two years later Princess Diana died in a car crash in 1997. She was a patron of the National AIDS Trust from 1991 until her untimely death.
