During the altercation, Vert pulled a gun and sent bystanders runner

He's also said to have slammed his gun into Byrd's stomach so hard she was hospitalized.

Bryd is pressing charges, and her flack accused Uzi of stalking her.

“Brittany has been trying to focus on her life and career,” Brianna tells TSR. “Uzi has been stalking Brittany since they broke up. Uzi is toxic and mentally and physically abusive. He has been for years.”
