Video has surfaced that shows rapper Offset‘s wife, rapper Cardi B yelling at him after he apparently fought with Migos rapper Quavo backstage at the Grammys on Sunday.

Sources tell TMZ the incident happened just before Quavo took the stage to perform his song “Without You” as a tribute to Takeoff during the “In Memoriam” segment of the show.

According to TMZ, the squabble started when The Grammys asked Offset to be a part of the tribute, but Quavo refused to let him take part.

Quavo and Offset got into a fistfight and had to be pulled apart by security.

Offset denied the reports on his Twitter page on Monday, writing, “What tf look like fighting my brother yal niggas is crazy [sic].”

However, Cardi was captured on cell phone video obtained by ET that showed her chastising him backstage.

“Both of y’all wrong! Both of y’all! This is not right. No, ni**a. Shut the f–k up,” she’s overheard saying.

The video clearly demonstrates who wears the pants in the Cardi B household.
