Things got ugly after New York City’s first-ever Miss Sri Lanka beauty pageant — when a caught-on-video brawl erupted between well-heeled revelers at the post-party with contestants on Staten Island.

Now-viral videos show a melee erupting during the Friday pageant’s after-party – with at least one tiara-wearing woman appearing to be caught in the fray.

It’s not clear what sparked the fight at The Vanderbilt in South Beach, where there is a large Sri Lankan population.

One of the pageant organizers, Sujani Fernando, told The Post none of the contestants were involved and all 14 were inside the building as the scuffle went down outside the venue.

The altercation follows a 2021 fight at a top pageant in Sri Lanka, during which the reigning Mrs. Sri Lanka ended up in cuffs after snatching the crown from the head of a rival she said should’ve been disqualified because she was divorced.

“This is the typical behavior of village Sri Lankans,” a social-media user wrote of Friday’s kerfuffle, according to the South China Morning Post. “Every event ends up in a brawl.

“From elders to children to women. They hit at each other with plastic chairs, umbrellas. It’s quite exciting to watch.”

Fernando, however, disputed the stereotype.

“Sri Lankans are good people,” she said. “It’s just a fight — fights happen, kids fight. That happens in any culture, any nationality, it doesn’t have to be Sri Lankans. We’re not that type of people.”

Fernando also said the viral fight and resulting rumors have overshadowed the hard work of the 14 young women who competed in the pageant.

“It’s very sad to see,” Fernando said. “The girls were so happy. You should see the effort, you should see the time they put into this, but they didn’t get a single minute to enjoy it.”

The Staten Island pageant, which looked to raise money for a Sri Lanka hospital amid economic turmoil in the nation, drew more than 300 guests, the Morning Post said.

Some critics were outraged that the fight broke out as Sri Lankan weathers economic turmoil and a supply-chain crisis, according to the paper.

 “First ever and last. What a disgrace,” wrote another user on a Daily Mirror YouTube video of the fight.

The video, shot from a distance, shows arguing at the venue that grows into shoving as several people try to play peacekeeper amid increasing screaming. Soon, several men are in full-out attack mode with fists flailing as women shriek, the videos show.

At least two men climb atop other guys on the floor and start hurling punches as more party-goers try to break up the fracas.  People are seen darting from the party in the aftermath, but some guests exiting appear ready to get into round two and charge each other, according to the video.

Chandra Muniweera said the fight happened close to midnight toward the end of the festivities. She denied anyone involved in the pageant was involved in the fight.

“We thought we had a very nice and a very good pageant, but unfortunately, this incident happened,” Muniweera told the Staten Island Advance.

Fernando said lies about the fight and pageant have been spreading online, which are hurting the reputations of the young women who competed.

“They’re building stories from those few videos, but they don’t understand the damage they’re doing to these 14 girls who were not involved in the fight,” she said. “I just feel so bad for the girls because people should let them enjoy the moment, enjoy their victory because they put in so much time.”

The NYPD said it had no calls or reports related to the fight.
