Diane Keaton passed away suddenly on October 11, 2025, at the age of 79, leaving fans around the world in mourning. While the exact cause of her death remains unknown, sources say her health had declined rapidly in recent months. Known for her iconic roles in films like Annie Hall and The Godfather, Keaton kept much of her health battle private, revealing only rare details to close friends.
One of her closest friends, Grammy-winning songwriter Carole Bayer Sager, shared that she had met Keaton just weeks before her passing and was shocked by how much weight she had lost. Keaton had spent much of her last months focused on family and away from the public eye. Her health deterioration took many longtime friends by surprise.
Keaton’s battle with health challenges began early in life. At 21, she was diagnosed with skin cancer, a condition that ran in her family. She often wore her famous hats partly to protect herself from the sun, something she neglected in her youth but emphasized later. In interviews, she openly discussed how cancer had affected her family, including her aunt and father.
In addition to cancer, Keaton battled bulimia for several years as a young woman, triggered partly by pressure to lose weight for a Broadway role. She described bulimia as an addiction she fought to overcome through therapy and counseling, sharing her story to help others with similar struggles.
In her final months, Keaton’s health declined quietly as she spent time away from the spotlight. Those close to her respected the family’s wishes for privacy during this difficult time. Today, she is remembered not only as a legendary actress but also as a person who confronted her health challenges with courage and grace.
