Let the liquor talk?

Four unidentified female Morgan Wallen fans got into a nasty fight Wednesday at the bathrooms at the country star’s concert in Pittsburgh’s PNC Park.

Aviral video of the brawl posted to social media starts with a woman in a white knit cardigan seemingly guarding a portable stall, which upsets a woman in a pink fringe top.

It’s unclear why exactly they are so angry as they shove and push each other until they fall into an open John — just as an innocent potty-goer rushes out of it.

Two more women — seemingly one on each team — enter the fight as the white cardigan fan’s head appears to be inches away from the unsanitary toilet seat.

One of the newcomers, wearing a blue romper and white cowboy boots, drags the other out of the porta-potty by her hair before kicking and punching the woman in the pink top.

The fight ends when the woman in the blue romper fails to close one of the women in the stall.

The fighter emerges from the loo, falling onto the ground in front of it.

The Post has contacted reps for Wallen, PNC Park, and Pittsburgh police for comment.

It’s unclear whether the “Last Night” singer even knew about the brawl, but people on X, the platform previously known as Twitter, had lots to say about it.

“These boots are made for STOMPING,” one joked.

“Was really hoping for swirly or something,” another chuckled.

“She just dropped a massive dump and came outside to a cat fight,” another said of the innocent bystander.

One person proclaimed: “There’s trash… and then there is white trash.”

Another user set up a poll,” Who would win in a fight?Jake Paul or The Porta Potty Women?”

Wallen, 30, continues his “One Night At A Time Tour” on Saturday at FedEx Field in Maryland.
