Katherine Schwarzenegger publicly supported her cousin Tatiana Schlossberg after she revealed her terminal cancer diagnosis.
Schwarzenegger, 35, took to Instagram on Sunday, November 23, to share several screenshots of the essay Schlossberg penned for The New Yorker which was published one day prior and detailed her battle with acute myeloid leukemia.
“This is a profound piece written by my extraordinary cousin, Tatiana. It’s been shared by many and should be read by all. I have only tears and anger reading that this is her reality. She has lived this experience with so much grace and I am in awe of her as a human, mother, wife, daughter, writer and fighter,” Schwarzenegger wrote. “I am and continue to be grateful for all the doctors and nurses helping her and encourage you to read her words about how the state of the country, the cuts and uncertainty, impacts and terrifies those in medicine and receiving treatment like Tatiana has been over the past year and a half, and continues to receive. Praying for and loving her and her family.”
The post comes after Schwarzenegger’s mother, Maria Shriver, publicly supported Schlossberg via her own Instagram tribute.
Schlossberg is the daughter of Caroline Kennedy and Edwin Schlossberg and a cousin of Robert F. Kennedy Jr.. Her essay noted that she learned of her cancer diagnosis after giving birth to her second child, a daughter, in May 2024. Schlossberg and her husband, George Moran, also share a 3-year-old son.

Shriver, who is a niece of the late U.S. president John F. Kennedy, shared similar praise for Schlossberg within her online own tribute. “If you can only read one thing today, please make take the time for this extraordinary piece of writing by my cousin Caroline’s extraordinary daughter Tatiana,” Shriver, 70, wrote. “Tatiana is a beautiful writer, journalist, wife, mother, daughter, sister, and friend. This piece is about what she has been going through for the last year and a half. It’s an ode to all the doctors and nurses who toil on the frontlines of humanity. It’s so many things, but best to read it yourself, and be blown away by one woman’s life story.”
Shriver continued, “Let it be a reminder to be grateful for the life you are living today, right now, this very minute.”
In Schlossberg’s essay, she noted that her doctor had noticed an imbalance in her white blood cell count, however initially put it down to labor and delivery complications. Further investigation later determined that she in fact has “a rare mutation called Inversion 3.”

She recalled, “I did not — could not — believe that they were talking about me. I had swum a mile in the pool the day before, nine months pregnant. I wasn’t sick. I didn’t feel sick. I was actually one of the healthiest people I knew. I regularly ran five to ten miles in Central Park.”
Schlossberg continued, “I had a son whom I loved more than anything and a newborn I needed to take care of. This could not possibly be my life.”
