Rapper Cardi B was reportedly injured when she tried to fight Nicki Minaj Friday night at a Manhattan Fashion Week party.

Cardi threw a shoe and left the party venue barefoot as she donned a ripped long red Dolce & Gabbana gown and was escorted out by security, witnesses told TMZ and People magazine. She left the party with an apparent large lump over her left eye after the altercation.

The row broke out at the Harper’s Bazaar ICONS party at the Plaza Hotel. Cosmopolitan cited sources that said the episode started shortly after Minaj allegedly stepped on the train of Cardi’s gown.

Videos posted on social media show Cardi B apparently lunging for the “Barbie Dreams” rapper amid chaos as security men and members of the women’s entourages scramble to stop the confrontation. Cardi B’s former “Love & Hip Hop: New York” reality co-star Rah Ali, a friend of Minaj, was also swept up into the altercation.

A witness told TMZ that Cardi told Minaj “Let me tell you something” and tried to get at Minaj but security stopped her. She then took off a shoe and hurled it at Minaj, but missed, sources said. TMZ reported that a member of the security detail elbowed her in the face, which caused the lump over her eye.

“It was bad,” a source told Page Six. “They were separated by security, but Cardi was still trying to get at her. She took of a giant red shoe and threw it at Nicki — who was being blocked up against a wall by huge security guard.”

Cardi B posted an Instagram comment afterward saying she has let a “lot of shit slide,” apparently referring to Minaj, though she didn’t mention her name in the post. “But when you mention my child … make comments about my abilities to take care of my daughter, all bets are fucking off!”

“All of the sudden there was a big commotion and everyone didn’t know what was going on,” a source told People.

Cardi’s first child with her husband Offset — daughter Kulture Kiari — was born July 10.

A long-simmering feud between Cardi and Minaj appeared to be resolved at the Met Gala in May when the rappers chatted and smiled. Beginning last year, the two began taking digs at each other in their songs, social media posts and during interviews.

A New York City Police Department spokesman told People said there were no arrests, but an investigation is continuing.
