6ix9ine is back at it.

After beefing with everyone from Lil Durk to Meek Mill, the notorious internet troll has set his sights on a new target–Fivio Foreign.

Last week, Tekashi announced his return to music with a demonic trailer for his new single, which drops tonight. “I’m THE BEAST they couldn’t contain. The industry most hated animal. APRIL 15th the KING OF NEW YORK IS COMING BACK. I’m going back home,” he captioned the clip.

But his claim to the throne didn’t sit well with Fivio, who challenged Tekashi’s “King of New York” title.

“5 Billboards in Times Square, Top 5 songs in NY on Apple at once, & articles in both Daily News & NY Times. Don’t ever let that n***a say he the King Of this city,” tweeted the “City of Gods” rapper.

6ix9ine responded by bringing up Fivio’s friend, Brooklyn rapper TDott Woo, who was fatally shot in February. “Didn’t his best friend just get shot in his head a month ago?” Tekashi commented on DJ Akademiks’ page. “He worried about billboards in Times Square….”

On Thursday, 6ix9ine returned to clown Fivio over his album sales. He responded to a report from Akademiks claiming that Fivio’s debut album B.I.B.L.E. was on track to sell 29,000 units in its first week.

“This y’all king? Not blackballed, all those features, the whole industry promoted that and now you Kanye and nicki sidekick even they even tried to help you promote,” he quipped.

Meanwhile, 6ix9ine continues to declare himself king of his city. “IM THE KING OF NEW YORK THIS MY CITYYYYYYYYY BROOKLYN,” he captioned his latest Instagram post.
