A woman fatally stabbed her lover during a wild brawl at a New York City nightclub

A 35-year-old woman was fatally stabbed with a broken bottle while trying to protect her lover from a disorderly mob during a massive brawl captured on video Sunday morning outside a Bronx nightclub.

Chaos erupted shortly after 4 a.m. outside Mama Dora’s Club on East Kingsbridge Road when a fight began between two groups as the bar was being evacuated, law enforcement sources and witnesses told The Post.

With his fists flying, one of the fighters – identified by locals as the woman’s husband – hit the ground, prompting her to intervene to try to protect him from his attacker, according to witnesses.

That’s when she was stabbed, and the fatal altercation was captured on surveillance footage.

What appeared to be a woman’s hair extension was left on the sidewalk along with shattered glass.

A man who witnessed the fight said: “They were fighting, and they were all outside.” He added: “(The victim) went out with her husband, and then the other men also went out

The witness, who requested to remain anonymous, said: “Then the two groups got into a fight.” “She got into the middle so they couldn’t get to her husband, and that’s when she was stabbed.”

A bystander said the perpetrator used a smashed bottle to deliver the fatal blow before the group fled the scene — with no arrests as of Sunday afternoon, even as broken glass continued to litter the sidewalk.

Police said the dead victim, whose identity was not revealed, suffered several stab wounds to the chest.

She was placed in a private vehicle and taken to BronxCare Health Systems and then transported to Lincoln Hospital, where she was pronounced dead, according to police.

Surveillance footage from a nearby business captured much of the chaos.

The dramatic clip shows a man wearing a yellow jacket jumping excitedly, then rushing forward and stabbing the woman before his companions appear to move away from him.

An eyewitness at the scene said the bloody attack left him speechless.

“There’s not much left in the world,” he said. “I have nothing to say. They need to find God.”
