Girls Get Into A Wild Brawl With Porta-Potty At The Morgan Wallen Show Inside MLB Stadium

Several girls got so pissed off at each other as they lined up for a portable potty at the Morgan Wallen show on Wednesday night...they actually fought each other -- and the fight wild was entirely filmed.< /p>

The incident happened inside the Pittsburgh Pirates home stadium at PNC Park...and while it's unclear what triggered the melee, it appears to be a dispute over who could use one of the toilets that triggered everyone.

You can see in the footage, two girls were arguing next to a portable potty... before they started pushing and shoving each other.

Eventually, the fight between the two spilled over into one of the open Johns...and despite the dire conditions, they continued to beat each other.

One of the girls' apparent acquaintances then came along to break off the relationship – and that's when things got a whole lot more violent.

The girl in the blue romper and white cowboy boots pulled one of the fighters by the hair and punched him. She then threw herself on another girl, before kicking her.

In the end, calmer spirits prevailed.

It's unclear if any arrests were made or if anyone was seriously injured...but Wallen's show ultimately went off without a hitch - the country star even donned a Pirates jersey to pay homage to the city. he was playing.
