Cardi B may have thrown a shoe at Nicki Minaj over a nixed collaboration with Future.

Jason Lee of Hollywood Unlocked reported Monday that Minaj, 35, prohibited Future from featuring on Cardi’s track “Drip,” threatening to drop him from their joint tour if he did.

“Future was [originally] on the track with Cardi,” Lee said. “Migos jumped on because Future had to jump off.”

Later that night, a demo of “Drip” featuring Future leaked on Twitter.

In July, a remix of Cardi’s track featuring Young Thug, Migos, Future and Hoodrich Pablo Juan dropped — without Cardi, 25, on it.

Reps for Cardi, Future and Minaj didn’t immediately return a request for comment, though Cardi previously claimed that Minaj tried to block artists from collaborating with her.

“I let you attempt to stop my bags, f—k up the way I eat,” Cardi wrote on Instagram immediately after their infamous New York Fashion Week brawl. “You’ve threaten [sic] other artists in the industry, told them if they work with me you’ll stop f–kin with them.”

Remy Ma previously accused Minaj of trying to sabotage her career as well, telling Wendy Williams in March 2017, “It was the behind-the-scenes things that you people would never know about, as far as trying to keep me off red carpets, trying to make awards don’t go to me or she won’t be in attendance, trying to get people to make bad reports about my album sales or just anything that I’m doing to make me look less and make her look better. When you’re trying to stop my bag or trying to stop me from taking care of my children, I have a problem with that.”

Cardi reportedly attacked Minaj, who was surrounded by security, at a New York Fashion Week party earlier this month, with the Bronx-born MC hurling a red high heel and getting a huge knot on her head in the process.

The brawl came after more than a year’s worth of back-and-forth disses. Minaj later called the fight “mortifying” and accused Cardi B of using payola to get hits. Cardi denied the claims.

Cardi may be winning in the end, however. Minaj and Future’s tour was postponed after reportedly suffering lackluster sales, while Cardi just nabbed her third No. 1 song on the Billboard Hot 100 with her Maroon 5 collaboration “Girls Like You.”
