What is The Idol's Epstein Joke?

Finkelstein, an official from Live Nation, is puzzled as to why Jocelyn has not postponed her forthcoming stadium tour. He conveys to Chaim, Jocelyn’s handler, that her absence of fresh tracks and recent negative publicity is causing him undue stress, manifesting as irritable bowel syndrome.
He says, “Right now, she’s making me have IBS, I’m f*cking sh*tting more blood than a kid at Epstein’s island,” he says.
