Bill Clinton had an affair with British-born socialite Ghislaine Maxwell, who is accused of helping recruit underage victims for notorious pedophile Jeffrey Epstein, according to a blockbuster new book.

The ex-president — who denies cheating on wife Hillary Clinton with Maxwell — reportedly engaged in the romps during overseas trips on Epstein’s private plane, a customized Boeing 727 that’s since become known as the “Lolita Express.”
