She was the daughter of diplomat Caroline Kennedy and artist Edwin Schlossberg, and a granddaughter of the 35th U.S. President John F. Kennedy and First Lady Jacqueline Bouvier Kennedy Onassis. In May 2024, shortly after the birth of her second child, Schlossberg was diagnosed with acute myeloid leukemia (AML), a rare and aggressive form of blood cancer with a mutation called Inversion 3.

In her impactful New Yorker essay titled "A Battle With My Blood," published on the 62nd anniversary of her grandfather's assassination, Schlossberg not only disclosed her illness but also publicly criticized her cousin, Robert F. Kennedy Jr., for his policies as Secretary of Health and Human Services, particularly regarding cuts to medical research funding.
