Payne was in San Antonio on Friday night with his Instagram model girlfriend, Maya Henry who is reportedly 19-years-old.
A video obtained by TMZ shows the singer getting into a shouting match with a few bouncers after they refused entry to his underage girlfriend.
Witnesses told the publication that Liam and Maya were able to get in at first, but later got into a scrap with security.
In the clip, you see Liam trying to come face-to-face with a bouncer but is being held back.
At one point you hear him say, “Don’t fucking push me again. I swear to God I’ll lay your ass out.”
Witnesses claim that Liam was, in fact, pushed to the ground (as you can tell by the dirt on his back) after he and Maya left and tried to reenter the bar.
He later took to Instagram to threaten legal action against the nightclub.
“Three of your bouncers just jump me for no reason whilst I was grabbing my ID,” he wrote.
“I took pics of the whole thing, look forward to seeing you in court, assholes.”
