Jocelyn Wildenstein, the New York socialite nicknamed “The Catwoman,” has died. She was 84.

Her partner, Lloyd Klein, reportedly told AFP that Wildenstein died of a pulmonary embolism in a Parisian palace on Tuesday, per Daily Mail.

A pulmonary embolism is a blood clot that blocks and stops blood flow to an artery in a lung, according to The Mayo Clinic.

The blood clot typically forms in a deep vein in a person’s leg and then travels to the lung. In rare cases, the clot can form in a vein in another part of the body.

Known for her cat-like features and addiction to plastic surgery, Wildenstein first made headlines in the late ’90s when she divorced her husband Alec Wildenstein, a wealthy art collector.

This is a developing story.
