Laura Plimpton died after suffering a brain aneurysm in her home early Monday (August 4) morning.

Martha Stewart sent the news of her sister’s passing to her lifestyle company’s staff: “My youngest sister, and the youngest of the six Kostyra siblings, Laura Kostyra Plimpton, passed away today in Norwalk Hospital. Laura worked for me and the company for more than 25 years.”

Stewart continued to describe her younger sister as “an extraordinary employee, mother, wife, and sister”.

The 59-year-old felt ill after her morning workout, so she called her husband, who took her to the hospital.

Plimpton’s organs were donated, per her request before she passed.

During a Larry King Live interview a decade ago, Plimpton spoke about the close bond she had with Stewart, almost a mother-daughter relationship in some ways.

Plimpton has three children.

Our thoughts and prayers go out to the Kostrya family. May she rest in peace.
