Per @tmz_tv, Quavo and Offset of the Migos got into a altercation last night at the Grammy's right before Quavo was set to take the stage to perform his tribute to Takeoff.
According to insiders at the event, Quavo and Offset got into a physical altercation and had to be separated shortly before Quavo went the stage to perform his song "Without You" as a tribute to Takeoff during the "In Memoriam" phase of the program.
The Grammys reportedly invited Offset to participate in the tribute, but Quavo reportedly refused to let him. According to reports, Quavo prevented Offset from joining him on stage, which sparked the brawl.
It's important to remember that Offset was estranged from the group at the time of Takeoff's murder, even though Quavo and Takeoff were very close. The song "Without You" by Quavo was written especially for Takeoff.
