The stunning revelation comes after the disgraced 66-year-old businessman reportedly hanged himself in his New York jail cell on Saturday.
He had faced numerous charges of trafficking dozens of underage girls for sex.
While sicko Epstein was widely known to be pals with Prince Andrew, there is no suggestion that he met the princess.
She is only mentioned after one of the billionaire’s former handymen claimed to have met “Princess Diana’s secretary with her children”.
The identity or even the nationality of the secretary is unknown, and it was not clear whether the documents meant the children were her’s or Diana’s.
Juan Alessi, a maintenance worker at Epstein’s plush Palm Beach mansion said he had met numerous celebs while working for the paedo.
He said: “I then listed Senator Mitchell, Prince Andrew, Princess Sarah Ferguson, Miss Yugoslavia, Miss Germany, Alan Dershowitz, Princess Diana’s secretary with her children, Mr Trump, Mr Robert Kennedy Jr, Frederik Fekkai and a couple of Noble prize winners as celebrities that I had seen while working for Mr Epstein.”
It was among more than 2,000 pages of bombshell testimony that related to a defamation case filed by Virginia Giuffre, who claimed to have had sex with Prince Andrew “three times”.
Mr Alessi didn’t give further context about the nature of the meetings.
He told The Sun: “I can’t think of any occasion when Mr Epstein would have any claim to say he had given hospitality to the Princess of Wales.
“To my knowledge, Princess Diana only ever went to Florida once and that was to Disney World (in 1993).”
Prince Andrew strongly denies any allegations made against him.
