Nicki Minaj's Manager Sues Her For Beating Him Up

Brandon Garrett, who says he was working as Nicki Minaj's manager earlier this year, is suing the rapper for beating and threatening him.

According to Garrett, things went left when he sent someone else to pick up a prescription for Nicki, which set the 42-year-old off.

"Are you f*cking crazy having him pick up my prescription? You have lost your f*cking mind and if my husband were here, he would knock out your f*cking teeth. You're a dead man walking. You just f*cked up your whole life and you will never be anyone, I'll make sure of it," Nicki allegedly said.

Then she smacked him so hard his hat flew off his head.  After her security team swarmed him, she struck him again, injuring his wrist.

He then locked himself in a bathroom for hours to avoid further beatings.

He's suing Nicki for assault, battery, and intentional infliction of emotional distress.
