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

A glamorous beauty pageant queen who wore nearly $1,000 Jimmy Choo heels on her big day allegedly owes 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 iconic venue.  

Self-described Instagram influencer Kaitlyn Rose Kennedy-Melanson, a certified behavior analyst recently crowned as Miss New York Elite, has not paid part of an alleged hotel bill from her September 2025 nuptials, which included such amenities as a penthouse suite and rooftop dinner with sweeping views of the Big Apple, the suit contends.

The food alone at the swanky hotel along Fifth Avenue was $100,000, according to the suit.

Kennedy-Melanson, the 2015 Miss Teen Massachusetts 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 venue, which boasts about its timeless elegance and five-star accommodations.

Even after “repeated demands for payment,” the hotel claims the Boston area-born 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.

Reached by The Post, Kennedy-Melanson called the hotel’s claims “bulls–t.” 

She claims that the St. Regis bill was paid in full, and the extra $37,000 was for an unused room block.

On review sites, both her and her husband left poor reviews of the venue last November, claiming that their $100,000 experience was “marred by poor service, unfulfilled promises, and unethical business practices.”

“From start to finish, we encountered repeated disappointments and mismanagement that no couple should ever have to endure,” her husband’s lengthy review states.

Kennedy-Melanson wedded Greg Melanson, who is the founder of a Big Apple-based investment sales brokerage firm that started in 2024 and focuses on middle-market commercial real estate transactions, according to his LinkedIn.

He is not named in the lawsuit.

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. 

Her Instagram was made private as the lawsuit publicly emerged Thursday, but according to her LinkedIn, she has been an influencer on the social media site for nearly 11 years.

“I have gained a high following through being Miss Massachusetts Teen in 2015, have been seen in various modeling campaigns, interviewed on the TV show, ‘Messier Mantra,’ along with being seen on MTV’s The Real World 2016,” she wrote on LinkedIn.

“I use my social media page to shed light on my personal platform regarding, anti-bullying. I am a youth advocate, and have worked closely with schools to implement an anti-bullying program.”

Kennedy-Melanson said on the online show “Messier Mantra” in 2018 that as a young girl, she had a speech problem that made it tough to speak publicly, leading her mother to get her involved in pageants.

Kennedy-Melanson noted she was bullied in middle school and high school, fueling her desire to work with children.

She is an applied behavior therapist, according to her LinkedIn.  

“As cliché as it sounds, I like wanna be someone that I needed when I was younger because I feel like they’re not enough people out there that wanna to do that,” she said in 2018 interview.
