Well, Cardi B's rumored feud with Nicki Minaj has got some new, explicit proof: Cardi reportedly tried to brawl with Minaj and her entourage late Friday night (September 7) in a scary scene that ultimately got Cardi escorted out of a New York Fashion Week party with a giant bump on her head.

According to People, Cardi showed up to the Harper’s Bazaar ICONS party first, and when she saw Minaj on the second floor during a Christina Aguilera performance, she went on the offensive.

The scene was f------ crazy,” a source told People. “It was entourage against entourage.”

At one point, Cardi even reportedly took off her shoe to try to throw it at Minaj, but ultimately, the fight was broken up and Cardi was escorted out (you can see her war wounds here).

“They had their altercation on the second-floor balcony, right above the red carpet. All of the sudden there was a big commotion and everyone didn’t know what was going on," the source added.

After the madness died down, Cardi posted a scathing but vague Instagram photo in which she seemed to insinuate that Minaj had triggered her by talking about her daughter, Kulture.

“I’ve let a lot of s--- slide! I let you sneak diss me, I let you lie on me, I let you attempt to stop my bags, f--- up the way I eat! You’ve threaten other artists in the industry, told them if they work with me you’ll stop f------ with them!! I let you talk big s--- about me!!” she wrote. “I addressed you once in person, I addressed you a second time in person, and every time you copped the plea!! But when you mention my child, you choose to like comments about me as a mother, make comments about my abilities to take care of my daughter is when all bets are f------ off!! I’ve worked to[sic] hard and come too far to let anybody f--- with my success!!!! Bitches talk all that s--- in they raps but in real life they pussy!! This s--- really is for entertainment!!”

The rappers' discord has previously only been the stuff of rumor, save for one interview with Zane Lowe on Beats One Radio in which Minaj said that she had been hurt by Cardi for being dismissive.

“The only thing that Cardi really, really, really hurt my feelings was the first interview she did after ‘Motorsport’,” she said. “I remember when I first came in the game, if a female of that stature had done a feature with me on it, I would only be singing their praises and saying, ‘Thank you.’ The first interview she did after ‘Motorsport’ came out, it really hurt me. She looked so aggravated and angry. And the only thing she kept saying was, ‘Oh, I didn’t hear that, I didn’t hear her verse.’ I was like…’What?'”
