This is going to make it tough to win Miss Congeniality.

A glamorous beauty pageant queen and social media influencer allegedly stiffed Midtown Manhattan’s luxury St. Regis Hotel out of the final $40,000 chunk of her lavish wedding bill, according to a lawsuit filed by the aggrieved inn.  

Kaitlyn Rose Kennedy-Melanson, a certified behavior analyst recently crowned as Miss New York Elite, has not paid her bill in full from her September 2025 nuptials, which included such amenities as a penthouse suite and $100,000 in food alone, the suit contends. 

Kennedy-Melanson, a Boston-born wanna-be influencer whose social media is rife with glam shots from her wedding, held her ceremony at the historic St. Patrick’s Cathedral, with dinner, dancing and the rest at the premiere St. Regis New York.

Even after “repeated demands for payment,” the hotel claims Kennedy-Melanson has not paid the final $37,000 — which comes to over $40,000 with interest — despite already handing over $106,000 for the unforgettable evening, according to court papers filed in Manhattan Supreme Court this week.

Kennedy-Melanson denied the allegation and declined to comment further.

The five-star venue alleges that it fully performed its duties, offering a high-end experience that included a five-hour open premium bar, room rentals — including an exclusive Penthouse for Kennedy-Melanson and her now-hubby — and a multi-course catering bill, which alone fetched $100,000.

Kennedy-Melanson received an invoice a week after the wedding, with payment due 30 days later, the hotel claims.

But since she failed to pay up, Kennedy-Melanson now owes 18% interest — plus all legal costs, according to a “dispute resolution” clause in the signed wedding contract, the suit says, forcing the hotel to take their former guest to court.

Kennedy-Melanson, who boasts over 111,000 followers on her Instagram page, has made over a dozen posts of her swanky wedding photos — including posing for a classic dip-kiss outside of the historic St. Patrick’s Cathedral as six separate shutterbugs snapped away. 

“Our version of a royal wedding,” the Sept. 20 post reads — five days after the hotel claims they sent her the final bill.

Other posts show off other luxurious trappings of her special day, including one photo with a nearly $200 bottle of Prada perfume and a pair of iconic Jimmy Choo “Sacora 85” lace sandals that retail for $950. 

Months after the wedding, Kennedy-Melanson was crowned National American Miss New York Elite, her third state title in the pageant circle, according to an Instagram post. 

She was also sued in 2022 over $3,1000 in unpaid rent for an East Harlem apartment, settling the matter two weeks later.
