Maria Shriver speaks out on Tatiana Schlossberg’s death, praises cousin Caroline Kennedy for being a ‘rock’

Maria Shriver shared a heartfelt tribute to Tatiana Schlossberg, after the young mother of two died Tuesday.

Schlossberg — the middle child of Caroline Kennedy and Edwin Schlossberg — died following her battle with acute myeloid leukemia, her family shared on Instagram.

Following the sad news, Shriver, who was Tatiana’s first cousin once removed, said she “cannot make sense” of Schlossberg’s death at just 35 years old.

“I return to this space today to pay tribute to my sweet, beloved Tatiana, who left this earth today,” Shriver posted alongside pictures of Tatiana over the years. “I return to this space to pay tribute and honor her loving and supportive family, who came together and did everything they possibly could do to help her.”

“I return to this space heartbroken because Tatiana loved life,” she continued. “She loved her life, and she fought like hell to try to save it.”

Shriver praised Schlossberg as a great journalist, and noted that she was “valiant, strong, [and] courageous.”

She also had kind words for Kennedy, 68.

Shriver, 70, wrote, “My heart has always been with my cousin Caroline ever since we were little kids. My entire being is with her now. What a rock she has been.”

Shriver vowed to keep Tatiana’s memory alive with Tatiana’s two children that she shared with her husband, George Moran: son Eddie, 3, and daughter Josie, 1.

“Those of us left behind will make sure Eddie and Josie know what a beautiful, courageous spirit their mother was and will always be,” she shared. “She takes after her extraordinary mother, Caroline.”

“May we all hold Tatiana’s family in our collective embrace not just today, but in the days ahead, and may each of you who read this know how lucky you are to be alive right now,” she noted. “Please pause and honor your life. It truly is such a gift.”

Tatiana revealed she had been diagnosed with acute myeloid leukemia in an essay she wrote for the New Yorker that was published in November.

She shared that doctors found her disease in May 2024 after she gave birth to her daughter, but that she had no obvious symptoms beforehand.

Doctors gave her only one year to live.

She heartbreakingly detailed how Moran — whom she married in September 2017 — supported her through her health battle.

“George did everything for me that he possibly could,” she noted. “He talked to all the doctors and insurance people that I didn’t want to talk to; he slept on the floor of the hospital.”
