Moments after the feds busted Ghislaine Maxwell Thursday for allegedly roping in underage girls for pal Jeffrey Epstein's perverted pleasure, fireworks started going off in the lives of certain billionaires and playboys who palled around with the two.

And not the happy Fourth of July kind.

Since no one was closer to the billionaire pedophile than Maxwell, whose network spanned from New York to France, Israel, Buckingham Palace and the Caribbean, those in the know are undoubtedly fretting over the dirt she could dish to keep herself out of jail.

Particularly after prosecutors vowed to "bring justice" to other potential enablers of Epstein's sex abuse and trafficking.

And her friend, TV host Christopher Mason, said he believes she had access to videotapes from all of Epstein's properties — and the footage has gone missing.
