Hollywood star George Clooney is grieving the profound loss of his older sister, Adelia “Ada” Zeidler, who passed away at age 65 following a courageous fight against cancer. The actor, known for his charm and resilience on screen, shared an emotional tribute calling her his “hero” and praising her unmatched bravery.

Ada died peacefully on December 19, 2025, surrounded by loved ones at St. Elizabeth Healthcare in Edgewood, Kentucky. Born on May 2, 1960, in Los Angeles to journalist Nick Clooney and Nina Bruce Warren, she was just over a year older than George. While her brother soared to global fame, Ada chose a quieter life in Augusta, Kentucky, working as a bookkeeper and elementary school art teacher. A talented artist herself, she was active in the local community, serving as a member of the Augusta Art Guild and even as grand marshal of the town’s Annual White Christmas Parade.

The siblings remained exceptionally close despite their different paths. Ada attended George’s lavish 2014 wedding to Amal Clooney in Venice, a rare public appearance that highlighted their bond. In 1987, she married retired Army captain Norman Zeidler, who sadly passed away from a heart attack in 2004. George participated in their wedding, reading scripture while their aunt, legendary singer Rosemary Clooney, performed.

Ada is survived by her children, Nick Zeidler and Allison Zeidler Herolaga (married to Kenny), her parents Nick and Nina, brother George and sister-in-law Amal, along with numerous extended family members. Her obituary describes a life filled with creativity, family devotion, and community spirit.

George’s tribute captures the depth of his sorrow: “My sister, Ada, was my hero. She faced down cancer with courage and humor. I’ve never met anyone so brave. Amal and I will miss her terribly.” The statement reflects the private strength Ada embodied, mirroring the resilience often seen in her famous brother.

This loss comes during a reflective time for Clooney, who has balanced blockbuster roles with philanthropy and family life as a father to twins. Ada’s battle and passing serve as a poignant reminder of life’s fragility, even for those connected to Hollywood’s elite.

The Clooney family has long roots in Kentucky, where George spent part of his childhood. Ada’s community ties there underscore her grounded nature amid her brother’s spotlight. Fans and peers have expressed condolences, honoring a woman who inspired those around her without seeking fame.

As the family prepares for a private funeral, George’s words echo the universal pain of losing a sibling—a confidante and lifelong companion. Ada’s legacy of bravery and kindness endures, touching lives far beyond her quiet hometown.
