The butler, who only identified himself as Gabriel, has come forward about the convicted pedophile's celebrity guests during his 18-year career working at the $8 million pied-à-terre, FranceInfo reported.

"I served crowned heads, diplomats, businessmen and politicians," he told the outlet.

Among the powerful guests he listed were former Israeli Prime Minister Ehud Barak and Prince Andrew, who would crash several nights at the apartment while Epstein was out of town, according to FranceInfo. The royal has since admitted he "regretted" his friendship with Epstein.

Gabriel said his boss also hosted Bill and Melinda Gates. The Microsoft founder has denied that he had a relationship with the disgraced financier — despite reports that he flew on Epstein's plane to Palm Beach in 2013.
