An Irish fashion designer who was found dead on a yacht in the Hamptons lived a jet-setting life of luxury with her glamorous pals.

Martha Nolan-O'Slatarra, 33, was discovered unconscious onboard a vessel named Ripple while it was docked at the Montauk Yacht Club around midnight Tuesday.

Good Samaritans attempted life saving measures, but East Hampton Town Police pronounced her dead at the scene. Her manner of death remains unclear and will be determined by the Suffolk County Medical Examiner's Office.

Irish-born Nolan-O'Slatarra, founder of fashion label East x East, created a ritzy lifestyle for herself that's often associated with Manhattan's elite.

The self-professed entrepreneur and brand growth consultant took rides on helicopters and private jets, videos posted on her TikTok account reveal.
