A beef has been brewing between New York rappers Casanova and Tekashi 6ix9ine, and the "GUMMO" rapper made things public during his December 30 gig at Club FREQ in New York. Tekashi was on stage with his crew and could be heard saying, "Shout out Casanova. We f***ed that n***a's b****."

There were unverified rumors earlier this week that some people affiliated with Tekashi tried to rob Casanova, which was fueled further after a video surfaced of Casanova facing off with a group of guys dressed in red. Casanova also released a video called "Set Trippin," which many believed was a diss track aimed at Tekashi. Many felt the line "If you want smoke ain't nothing we gotta speak 'bout/See you with that red flag on what that be bout?" was aimed specifically at Tekashi.
