RHONY Alum Carole Radziwill Reacts to Tatiana Schlossberg’s Death

The Real Housewives of New York City alum Carole Radziwill shared a heartfelt tribute to Tatiana Schlossberg after her death at 35.

“I woke up to the news that Tatiana Schlossberg passed away last night. Although I hadn’t seen her in many years, the news brought back memories,” Radziwill, 62, captioned an Instagram post on Wednesday, December 31.

The former reality star was married to Anthony Radziwill, the nephew of Jacqueline Kennedy Onassis, from 1994 until his death in 1999. Anthony was 40 years old and battled testicular cancer.

Schlossberg, meanwhile, was the granddaughter of Jacqueline and John F. Kennedy and daughter of Caroline Kennedy. She died on Tuesday, December 30, one month after announcing her acute myeloid leukemia diagnosis.

“She was thirty-five. Not much younger than my late husband, Anthony when he passed away,” Carole’s tribute continued. “The arithmetic of loss never makes sense to me — who stays, who goes, and when. Some people are spared and others are not, and there is no moral logic to it. That is the part I still can’t accept.”

Carole reflected on the Kennedy family’s loss, writing, “Remembering the two of them together, it’s impossible not to feel how profoundly unfair it all is — how brief some lives are allowed to be, and how long the rest of us are left to remember them. My thoughts are with her family today.”

Carole concluded her message by encouraging fans to donate to the Kennedy Library in Schlossberg’s honor. “No one from her family has asked for donations but it feels like a sweet thing one can do and I’m sure would be appreciated. I put the link in my bio. 💔,” she wrote.

Tatiana is survived by her husband, George Moran, and their two children, Edwin and Josephine, as well as siblings Jack and Rose, mom Caroline and dad Edwin Schlossberg.

Late President John F. Kennedy’s granddaughter Tatiana Schlossberg made an impact after going public with her health battle. Tatiana wrote an essay for The New Yorker in November 2025, revealing that she had been diagnosed with acute myeloid leukemia. Doctors estimated that she had one year to live. “I did not — could not — […]

While reflecting on her cancer battle in a November essay for The New Yorker, Tatiana revealed she was diagnosed in May 2024 after giving birth to her daughter. Doctors discovered an imbalance in her white blood cell count, which was believed to be related to her pregnancy, but it was later confirmed to be a “rare mutation called Inversion 3.”

Tatiana was told her illness could not be “cured by a standard course” of treatment.

“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,” she wrote. “I had a son whom I loved more than anything and a newborn I needed to take care of.”

Tatiana began a clinical trial of CAR-T-cell therapy in January before learning her cancer was terminal. She noted that her “first thought” was about what her kids would remember after her death.

“My son might have a few memories, but he’ll probably start confusing them with pictures he sees or stories he hears,” she wrote. “I didn’t ever really get to take care of my daughter — I couldn’t change her diaper or give her a bath or feed her, all because of the risk of infection after my transplants. I was gone for almost half of her first year of life. I don’t know who, really, she thinks I am, and whether she will feel or remember, when I am gone, that I am her mother.”

Tatiana also praised her husband, who “did everything for me that he possibly could” throughout her health battle.

“I know that not everyone can be married to a doctor, but, if you can, it’s a very good idea,” she added. “He is perfect, and I feel so cheated and so sad that I don’t get to keep living the wonderful life I had with this kind, funny, handsome genius I managed to find.”
