Bianca Jagger wants to set the record straight about a certain night at Studio 54, which has haunted the annals of night life lore since 1977. “Mick Jagger and I walked into Studio 54,” she wrote in a letter to the editor in the Financial Times, finally setting to rest the rumors that she rode into the famed nightclub on a white horse.

As with most rumors, the story has some basis in fact. Fashion designer Halston threw a 30th birthday party at Studio 54 for Jagger, who at the time was married to Rolling Stones frontman, Mick Jagger. At the party, a naked giant covered in gold glitter led Bianca, clad in Halston and Manolo Blahniks, around the night club on horseback. The moment was captured by noted fashion photographer Rose Hartman and the image went whatever was the 1977 equivalent of viral, slowly becoming emblematic of the excesses (read: fun) of the era and eventually becoming a legend.

However somewhere along the way, the story was twisted to include the detail that Jagger rode into the nightclub on the horse, which would certainly be a memorable feat. However, Jagger took to the Financial Times today to declare that detail preposterous and, as an animal rights defender, downright offensive. In the letter to the editor, she wrote: “It is one thing to, on the spur of the moment, get on a horse in a night club, but it quite another to ride in on one.”

She explained that the club’s owner, Steve Rubell, had brought the horse into a club as a lark, after seeing a photo of her riding one in her home of Nicaragua. When she saw the horse inside the club, Jagger thought it would be fun to hop on and take it for a quick spin. Contrary to rumor, she did not ride the white horse down 54th street and into the velvet-roped doors of Studio 54. In her letter to the editor, Jagger wrote: “I often ask myself how people visualise this fable . . . Where was Mick during this time? Was he holding the reins and pulling me and the horse through the streets of New York, or following submissively behind me!?”

She closed the note with the hope that her letter would finally “put this Studio 54 fable — out to pasture.”
