Queen mainman Freddie Mercury took Princess Diana into a gay bar dressed in drag, according to comedian Cleo Rocos.

In a serialisation of her new book The Power of Positive Drinking published in the Sunday Times, Rocos revealed that she, Mercury and Kenny Everett went pubbing with the late Princess in the 80s.

She said, however, that to get Diana into the South London pub took a bit of cunning disguise. Rocos said:

"Scrutinising her in the half light we decided that the most famous icon of the modern world might just - just - pass for a rather eccentrically dressed gay male model."

She continued: "The place was full. It took an absolute eon to edge our way to the bar, with person after person cheerfully greeting us. It was fabulously outrageous and so bizarrely exciting. Our hearts pounded with every new leather-clad hairy body that approached, but no one, absolutely no-one, recognised Diana. 

"On we inched, through the leather throngs and thongs, until finally we reached the bar. We were nudging each other like naughty schoolchildren. Diana and Freddie were giggling, but she did order a white wine and a beer. Once the transaction was completed, we looked at one another, united in our triumphant quest. We did it!"
