The apparent beef between Lil Tecca and Lil Mosey gets a new development.

On Wednesday night (Oct. 30), Tecca performed at the El Rey Theater in Los Angeles. During his set, his fans began chanting "Fuck Mosey!" in response to an Instagram Live diss from the 2019 XXL Freshman the night before. Tecca did his best to stop the yelling, however.

"No, that's not what we doing here!" Tecca told the crowd as they all erupted into the chant.

It's currently unclear exactly where the beef stems from, but fans point to an Instagram Live that Mosey did earlier this month. On Oct. 17, a Mosey fan page shared a clip where the young rapper freestyled on IG Live and disses a "nerd" that wears glasses who is stealing his rhymes.

“He taking his glasses off, that nigga a nerd/Fucking liar, I put him in the dirt," Mosey says in his freestyle. "I say it two times/He stealing my rhymes!”

On Tuesday (Oct. 29), Mosey called Tecca out by name on another Instagram Live session after a fan asked him whether he'd collaborate with the 17-year-old.

"Alright so you said, 'Are you dropping a song with Tecca?' Fuck Tecca!" Mosey said. "Fuck is you saying? Don't ever bring his name up in my Live one more time."

Lil Tecca's latest effort, We Love You Tecca, dropped in September and debuted in the No. 4 spot on the Billboard 200, moving 68,000 equivalent album units in its first week.
