It’s a beef of the Lil’s.

During Lil Tecca’s concert at the El Rey Theater in Los Angeles, fans chanted “F**k Mosey” in response to the rapper’s ongoing feud. Lil Mosey seemingly ignited the beef earlier this week during an Instagram Live session. The 2019 XXL Freshman responded to a fan who asked if Tecca would be featured on Mosey’s upcoming album, Certified Hitmaker.

“F**k Tecca!” Mosey said during the Live. “F**k is you saying? Don’t ever bring his name up in my Live one more time.”

The “Stuck In A Dream” rapper also previously shared a freestyle to his Instagram, where he dropped verses that fans believe are directed at Tecca.

“He taking his glasses off, that ni**a a nerd/F**king liar, I put him in the dirt,” he raps in the freestyle. “I say it two times/He stealing my rhymes.”

Lil Tecca, who’s pretty new to the scene, attempted to quiet down the chanting crowd at his Wednesday night show (Oct. 30).

“No, that’s not what we doing here!” he told the audience.

Tecca initially gained recognition from his song “Ransom.” Released on his debut We Love You Tecca mixtape, the track debuted at No. 93 on the Billboard Hot 100, before traveling up the charts to No. 4. This past August, Tecca and Juice WRLD released a collaborated remix of the song, which went on to gain viral momentum. We Love You Tecca debuted at No. 4 on the Billboard Hot 200 upon its release this past September.

Mosey, who hails from Washington, is set to release second his studio album, Certified Hitmaker, on Nov. 8. The project will include features from Gunna, AJ Tracey, Trippie Redd and Chris Brown on the previously released “G Walk.” Certified Hitmaker will serve as the follow up to Mosey’s debut effort, Northsbest, which he released last year.
