TROUBLE: Cheyenne Jeudy was having the time of her life at her Sweet 16 party in Queens -- until goons from a neighboring party invaded the soiree and allegedly groped her friends and beat up her cousin.
It was supposed to be a pretty cheerleader's dream Sweet 16 party.
But the $50,000 celebration turned sour when thugs attending a wedding at the same Queens catering hall crashed the affair, molested teenage girls and walloped the guest of honor's cousin, a new lawsuit says.
Cheyenne Jeudy spent months preparing for her blowout bash, which included the teen performing three choreographed dance routines.
Her mom, Denise, a city cop, spent two years preparing for the party, attended by relatives from as far away as Trinidad and Canada.
But according to a lawsuit filed by Denise Jeudy, the festivities turned ugly because Russo's on the Bay, a Howard Beach catering hall, had no security in place to prevent guests at another party from molesting young girls at the Sweet 16 and beating up her nephew outside.
The mayhem ruined what had been a perfect night for Cheyenne, a pretty cheerleader at Lawrence HS on Long Island who aspires to join her mother in the NYPD.
"They [the party crashers] were drunk. They were feeling my friends up while they were dancing, pulling them down on the floor with liquor in their hands," Cheyenne said. "I was embarrassed. I was pissed off."
The party was supposed to be every girl's fantasy -- and Denise Jeudy and her transit-worker husband, Frank, went all out trying to make the day special for her only daughter.
She said she spent thousands of dollars on choreography, costumes for Cheyenne and the other dancers -- including traditional Carnival outfits worn by revelers in her native Trinidad.
She booked the bridal suite at Russo's on the Bay, what she thought was a "classy place," after attending several affairs there.
She also splurged on limousines, tuxedos for her three sons and an ivory gown with a train for Cheyenne's grand entrance.
"She's the only daughter I have," Denise Jeudy said. "This is our princess."
Cheyenne wound up in tears by the end of the night after one of the wedding guests was arrested for allegedly stomping her cousin, Anton Lowe, who had gone outside for a smoke after chasing some of the interlopers from the Sweet 16.
The four men -- Neville Laibhen, Einstein Laibhen, Steve Perrin and Andy Delbrun, all of Brooklyn -- were arrested on assault and weapons charges after the July 2008 dust-up and pleaded guilty to disorderly conduct at arraignment.
The quartet and Russo's on the Bay were all named as defendants in the lawsuit, which was filed in Queens Supreme Court earlier this month and demands several million dollars from each defendant.
Perrin said he was just part of the fight and had nothing to do with the party crashing.
The others did not return calls for comment.
