Diane Keaton, the Oscar-winning actress, died at the age of 79 in California on October 11, 2025. The exact cause of her death has not been publicly disclosed. According to reports, her health declined very suddenly in the months before her passing, which was unexpected for someone with her strength and spirit. She was surrounded by her closest family during her final months, and her family chose to keep details of her health private, even from longtime friends. The Los Angeles Fire Department responded to a medical call at her home shortly before she was taken to the hospital. She is survived by two children and remembered fondly by many in the film industry for her iconic roles and talents. Diane Keaton had a history of battling bulimia and basal cell carcinoma (a form of skin cancer) earlier in her life, but no direct connection to her cause of death in 2025 has been reported yet.
