Reclusive Diane Keaton's chilling final hours are being laid bare by close friends and a shocking 911 recording as blindsided acquaintances of the late Annie Hall icon reveal they didn't even know she was ill.
RadarOnline.com can reveal the 79-year-old Oscar winner was surrounded by loved ones – including her adopted children, daughter Dexter, 29, and son Duke, 25 – when an emergency call was made around 8 a.m. on October 11 in a desperate but futile attempt to save her life.
A 911 dispatcher immediately sent paramedics to Keaton's California home – with audio to the Los Angeles Fire Department citing a "person down."
Diane's Death
Paramedics rushed Diane Keaton to a California hospital, where the Oscar winner was pronounced dead.
The First Wives Club cutup was rushed via ambulance to a nearby hospital, where she was pronounced dead.
"She declined very suddenly, which was heartbreaking for everyone who loved her," a friend said. "It was so unexpected, especially for someone with such strength and spirit."
Another source told RadarOnline.com: "Diane was very private about her health. She had several battles with skin cancer in her life that required surgeries, but she kept her grim condition to herself and really wasn't seeing people in recent months."
Diane's Secret Health Battles
Keaton battled skin cancer for decades, undergoing multiple surgeries.
The Godfather actress was always svelte, carrying about 125 pounds on her 5-foot-6 frame. But acclaimed songwriter Carole Bayer Sager said she was shocked to see her close friend had become skeletal in her final days, with her weight dipping to a mere 100 pounds.
"I saw her two or three weeks ago, and she was very thin," recalled Sager, who cowrote Keaton's only solo single, the 2024 track First Christmas.
She also shared Keaton's health was compromised by the wildfires that devastated Los Angeles in January.
"She had to go to Palm Springs because her house had been damaged inside," Sager explained. "When she came back, I was stunned by how much weight she had lost."
The 'Godfather' star privately battled bulimia and skin cancer during her decades-long Hollywood career.
According to a source, Keaton was never "part of the hard-partying crowd in Hollywood," but still faced numerous health battles – including the eating disorder bulimia, which began early in her acting career and required therapy to conquer.
Keaton also developed basal cell carcinoma in her early 20s, and 30 years later, underwent two surgeries for squamous skin cancer.

"Her death was on her own terms."
