He was often thought of as a wild entertainer, thanks largely in part to his extravagant performances while fronting Queen.
But those closest to the Zanzibar-born hitmaker often noted how away from the spotlight, the 45-year-old could be quite shy.
As well as amassing a huge fanbase across the globe, Freddie was also revered by other legendary musicians, including the likes of Sir Elton John, David Bowie and Liza Minnelli.
And so it was no surprise that when fronting a band called Queen, members of the monarchy would become entranced by the Bohemian Rhapsody star.
According to reports, this was most prominently seen with his friendship with Princess Diana.
The pair would reportedly get up to “mischief” together, and often enjoyed evenings in watching shows such as The Golden Girls, and nights out at gay bars.
Their reported relationship was detailed in The Power of Positive Drinking, written by actress Cleo Rocos, who recalled one of their more hilarious encounters together.
In one episode, Cleo noted, Freddie and comic Kenny Everett even tried to smuggle Diana into a gay bar without the public catching on to who the royal was.
Cleo told how the group started the afternoon by drinking champagne and watching Golden Girls at Kenny’s house, with everyone improvising their own “naughty” storylines for the show.
When the afternoon turned to evening, the trio – Cleo claimed – were ready to go out and started planning how to smuggle Diana into London gay bar Royal Vauxhall Tavern.
At the time, Diana was one of the world’s most recognised faces, so was initially concerned about the paparazzi seeing her going out clubbing.
Yet, Cleo explained that Diana then went into “full mischief mode”, with Freddie convincing the Princess of Wales’ to “have some fun”.
They decided to try and disguise Diana by dressing her in male clothes, and wouldn’t go out until they were sure she would “pass for a rather eccentrically dressed gay male model”.
In her book Cleo described Diana as “looking like a beautiful young man”.
She recalled how the group “inched through the leather throngs and thongs” to get to the bar, before Diana was able to order a white wine and beer.
Cleo added: “We were nudging each other like naughty schoolchildren. Diana and Freddie were giggling.
“Once the transaction was completed, we looked at one another, united in our triumphant quest. We did it!”
Some dispute the story’s validity, with Freddie’s PA and close friend Peter Freestone claiming the singer “never met” Princess Diana.
He even noted that when given the chance to meet the Princess of Wales at Live Aid, Freddie was nowhere to be seen.
Peter added last year: “You see Brian May and Roger Taylor in the royal box. Freddie didn’t go.
“He was more interested in being with friends backstage, talking with Elton John, hanging out with his people. His friends were always the most important to him.”
