A Luigi Mangione fan girl cosplaying as an independent “journalist” vulgarly snapped at a Post photographer when confronted about where her work could be viewed outside Manhattan criminal court Tuesday morning.

Lena Weissbrot’s pottymouth was exposed after a brief court hearing, where the accused CEO shooter was a no-show because of an error by the Manhattan District Attorney’s Office.

As Weissbrot was ranting about the ills of health insurance, a Post photographer cut in to ask why her press pass wasn’t visible and if she works for a media outlet.

When she was asked where her work could be seen, she replied, “Suck my c–k dot com.”

Weissbrot is among a crew of Mangione supporters who were granted press passes by the mayor’s office and show up to “cover” the case involving the murder of UnitedHealthcare CEO Brian Thompson in midtown Manhattan.

Mangione was supposed to be court Tuesday, but the hearing was shelved off to Wednesday after prosecutors failed to contact the defendant in time.
