A Fatburger employee was slashed early Sunday morning when Floyd Mayweather and T.I. got into a chair-throwing, all-out brawl at the Las Vegas burger joint.

According to TMZ, the fight was over T.I.'s wife, Tiny, who recently posted an Instagram photo of her posing with Mayweather's daughter.

Mayweather and T.I. apparently have a history of arguing over Tiny, who was also photographed at Mayweather's fight earlier this month.

When the pair crossed paths at a Fatburger restaurant, T.I. reportedly confronted Mayweather about the photos. Mayweather, in a moment caught on video, told T.I. to "control your bitch," and the argument quickly escalated into a chair-throwing melee.

Rolling Stone reports an employee was slashed during the fight, but refused medical treatment and declined to cooperate with Las Vegas police.

Mayweather has since apologized for referring to Tiny as a bitch.

"I don't want to say that about Tiny," he said. "So I do apologize to Tiny because she cool people. She never been disrespectful to me."
