Cardi B and Nicki Minaj Get into Fight During Fashion Week

The New York Fashion Week fight heard 'round the town happened tonight when Cardi B and Nicki Minaj were involved in a heated altercation during the Harper's Bazaar Icon party at The Plaza Hotel.

In videos captured by both E! News and fellow guests, the two rappers were seen in a scuffle towards the end of the party. An insider tells us Minaj was mingling with guests and keeping to herself when Cardi lunged at her and began shouting. Minaj then didn't move and continued on with her night. Footage also appeared on social media and showed Offset's leading lady throwing a red high heel at Minaj. She even accidentally revealed her own underwear during the tussle.

"It was so fast!" an eyewitness tells E! News. "I heart someone screaming?everyone recognized Cardi's voice?people either got out of the way or took out their phones and started filming. Nicki was surrounded by a bunch of guards and barely even looked at her. Next thing you know, shoes were flying and Cardi was on her way out."

Police tell us they responded to the altercation at 11:00 p.m. and that there were no visible injuries. However, there appeared to be a mark above the new mother's left eye.

A source also tells E! News the "staffers were mortified" by the incident.

"This event took months of planning, and it's meant to be the most exclusive and glamorous party during [New York Fashion Week]," the insider said. "This kind of behavior overshadowed months of hard work and an otherwise fabulous night."

Cardi was seen escorted out of the private event with her team in tow.

Shortly after the fight, Cardi took to Instagram to vent her frustrations over the "Bed" rapper.

"I've let a lot of s--t slide! I let you sneak diss me, I let you lie on me, I let you attempt to stop my bags, f--k up the way I eat! You've threatened other artists in the industry, told them if they work with me you'll stop f--kin with them!! I let you talk big s--t about me!!"

She continued, "I addressed you once in person, I addressed you a second time in person, and every time you copped a 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--kin off!! I've worked too hard and come too far to let anybody f--k with my success!!!!"

Cardi concluded by writing, "Bitches talk all that s--t in they raps but in real life they p--sy!! This s--t really is for entertainment!!"

Nicki has yet to publicly comment about what went down tonight at the NYFW party, but it's only a matter of time before she tells her side of things (cue the next installment of Queen Radio).

She did, however, take to social media after the argument?but not to talk about the Invasion of Privacy star. Nope, instead, Minaj showcased her leopard print ensemble in a series of Instagram pics that focused on what the night was really supposed to be about: fashion.
