Martha Nolan-O’Slatarra’s boyfriend gives heartbreaking tribute at designer’s funeral after she was found dead on Montauk boat

The Manhattan fashion designer found dead on a boat at the swanky Montauk Yacht Club was laid to rest in her native Ireland Wednesday — with her grief-stricken boyfriend telling mourners she had a way of “lighting up every room.”

Martha Nolan-O’Slatarra’s funeral was held at the Cathedral of the Assumption in the tiny Irish town of Carlow — about 50 miles from Dublin — early Wednesday.

The 33-year-old’s heartbroken partner, Nicholas DiRubio, was among the loved ones spotted carrying her coffin from the packed church.

“Martha had a special way of lighting up every room she walked into, whether it was her signature ‘Hi’ or her famous hand gestures,” DiRubio told mourners during the service, according to the Irish Mirror.

“One couldn’t help feel her positive presence in every space she entered,” he continued.

“Martha had a way of putting people first. She loved helping people and many of you in this room have been lucky enough to experience that love, whether it was telling you to cop on or focus on the good in this life, or just being a shoulder to lean on.”

The designer’s passport and make-up brushes, as well as a US and Irish flag, were on display inside the church during the service.

Nolan-O’Slatarra, who moved to the Big Apple in 2018 where she ended up co-founding her East x East swimwear brand, was found dead earlier this month where she was summering in the Hamptons.

She was found unresponsive on a boat named “Ripple” — one of two belonging to insurance mogul Christopher Durnan — in the early hours of Aug. 5.

The Irish beauty’s death is being eyed as a possible accidental drug overdose given her body didn’t show any evidence of violence, police sources have said.

Her grieving family, however, has demanded further investigation.
