Diane Keaton’s Cause of Death Revealed – Statement From Her Family
The family members of the “Looking for Mr. Goodbar” actor have spoken out, disclosing the reason behind her passing and their wishes for her to live on in memory.
After Diane Keaton passed away, shock erupted on social media as users struggled to cope with the unexpected loss and the revelations made by her family.

“What?!,” one astonished netizen wrote. What a terrible thing, oh! I didn’t anticipate that. So depressing. “Was it not skin cancer?” inquired another. “That’s so fixable,” a third person said. Sad 😢.
“I don’t believe it,” said one commenter, while another said, “Wow no way!” According to a another commenter, “Hmmm 🤔 that’s suspicious.”

One person said, “pneumonia.” A personal reflection on “pneumonia” was offered by another. It’s possible for something to be so deadly. Last year, I nearly died from it. It’s not as easy to fix as one may believe.
The family sent a statement to People on October 15, 2025, amid a flurry of emotional responses on the internet:

“The Keaton family are very grateful for the extraordinary messages of love and support they have received these past few days on behalf of their beloved Diane, who passed away from pneumonia on October 11.”
However, Keaton’s kindness endures even after she passes away. Her family urged everyone to show kindness in remembrance of her legacy:
“She loved her animals and she was steadfast in her support of the unhoused community, so any donations in her memory to a food bank or an animal shelter would be a wonderful and much appreciated tribute to her.”
According to many close to Keaton, her health had been slowly declining in the months before she passed away, even though her family confirmed pneumonia as the cause of death.

Longtime friend and Oscar-winning lyricist Carole Bayer Sager has revealed the disturbing circumstances of her last encounter with the late celebrity in a heartbreaking new discovery that she shared with the same outlet. The visit took place a few weeks prior to Keaton’s untimely death at the age of 79.
Carole Bayer Sager Reacted to a Startling Appearance
Keaton’s final interaction with the songwriter left a lasting impression. Sager said, “I saw her two or three weeks ago, and she was very thin,” to the source. “She had lost so much weight.” She was astonished by the abrupt change.
Sager spoke with sincere grief and incredulity of her beloved friend’s remarkably fragile appearance. Earlier this year, the adored actress was temporarily relocating to Palm Springs due to the January wildfires.
Sager disclosed that she had seen her close friend less this year due to the fires, saying, “She had to go to Palm Springs because her house had been damaged inside and they had to clean everything.”
“She was down there for a while, and when she came back, I was kind of stunned by how much weight she’d lost,” the songwriter added, her comments resonating with the anxiety of someone who was watching a silent fight.
There’s Still Light in the Dark
In Sager’s opinion, Keaton was still a creative force despite the obvious symptoms of her deteriorating health; she was lively, inquisitive, and full of brightness. Sager recalls with fondness, “She was a magic light for everyone,” “I simply adored her. Her energy simply illuminated a room, demonstrating how unique she was.
Diane Keaton never let illness stifle her natural passion, whether she was taking pictures of her surroundings or working on artistic endeavors.

“She took pictures of everything she saw and was cheerful and optimistic. “She never stopped creating; she was incredibly creative,” Sager revealed.
The November 2024 release of their musical duet, “First Christmas,” may have perfectly encapsulated that creative zeal. Sager remembers the song, which was co-written with Jonas Myrin, as Keaton’s lone solo single. “She loved recording this song,” Sager remarked. “She was almost childlike about it.” The event served as an emotional release in addition to being a means of creating music.
“She is a fantastic actress, so when she sang it, she was kind of acting it. She was so genuine.” Then, while singing it, she would begin to cry. Keaton’s musical gal friend remarked, “But she did such a beautiful job.”

A Complete Icon
Sager also like Keaton’s signature style, which was a whimsical yet sophisticated combination that was always admired.
“She went to the movies always dressed like she was about to shoot another scene for ‘Annie Hall,'” Sager said. She would put on her belts, jackets, caps, and loose-fitting slacks. She made herself into a fashion icon.

The gifted songwriter also talked about how she, Keaton, and fellow A-lister Bette Midler were all members of a monthly “movie group.” Midler voiced her anguish and sadness at the tragic news through her own tribute.
Although Sager’s poignant story provides insight into Keaton’s last years, the actress’s struggle with health problems dates back to her 20s, far before her recent deterioration and death.
A Silent Reduction Nobody Was Anticipated
The adored actress “declined very suddenly,” according to sources close to the “Book Club” star, leaving her inner circle “heartbroken” and in shock. According to a lifelong friend, “It was so unexpected, especially for someone with such strength and spirit.”
Keaton’s world shrank as the end approached. “She was surrounded in her last months only by her closest family members, who decided to keep things very private,” the person continued. Not even close friends knew exactly what was going on. The gentle dignity with which she always handled life’s most trying times is echoed in those words.

Skin Cancer: The Unspoken Struggle That Influenced Her Campaign
Keaton’s battle with disease started quite early in life. She was diagnosed with basal cell carcinoma, a type of skin cancer, at the age of 21. She developed squamous cell carcinoma years later and had to have two surgery to remove the malignant cells.
The actress became an outspoken supporter of sun safety because she was determined to save others from suffering the same fate. She boldly declared that she never left home without the brand’s sunscreen when she joined L’Oréal Paris as a spokesman in 2006.
Keaton once remarked, “It’s a family history,” while considering her family’s medical background. I recall that my aunt Martha’s nose was amputated due to severe skin cancer. My brother and father both have basal skin carcinoma. This skin cancer is difficult. It is for this reason that you must use sunscreen.
However, she also acknowledged that she had to learn the hard way and that she had disregarded skin protection when she was younger. She sadly acknowledged, “I didn’t start sun care until my 40s,” calling her previous negligence stupid.

A Covert Battle with Bulimia
Keaton battled a terrible eating condition that almost ruined her long before Hollywood glamorized being slim. She was told to shed 10 pounds when she was barely 20 years old and getting ready for a Broadway part; this demand set her on the path to bulimia. In an interview with Dr. Oz in 2014, Keaton revealed the grim reality:
“I am an addict because all I did was satisfy my appetite. It’s accurate. I will always be an addict, even though I’m in recovery. I have a tendency to become addicted.

Keaton’s account of her eating patterns during the worst of her illness is still startling. A feast of fried chicken, French fries with blue cheese and ketchup, television dinners, a whole cake, three banana cream pies, and pounds of candies were among the 20,000 calories the actress admitted she would devour each day before purging.
The Point at Which Recovery Begins
When someone close to her voiced concerns, she eventually sought assistance. “Somebody mentioned that I seemed to have some mental issues, so I went to an analyst,” Keaton said. Five weekly therapy sessions marked the beginning of her healing journey, a taxing emotional process that gave her back control over her life and body.
Despite her success and accolades, the actress hardly ever discussed her difficulties in public. In private, however, she confronted them with silent fortitude, drawing power from reflection rather than show.
A Legacy of Grace and Resilience Keaton’s life was much more nuanced than the cheerful grins and lighthearted eccentricities she conveyed on television. Beneath the glamour was a lady who, although facing intense personal struggles, inspired millions with her openness, humor, and genuineness.

Even the brightest stars have dark sides when they are not in the spotlight, as her story poignantly reminds us. Even though Keaton kept a lot of her suffering hidden, her bravery and candor in facing her ailments would live on in her legacy.
Final Moments Unveiled as the Cause of Death Is Mystery
Hours after her death, TMZ was able to acquire terrifying dispatch tapes from the instant emergency personnel arrived to Keaton’s house in the Los Angeles region. A voice said, “Rescue 19, person down…” before providing her address.

The outlet claims that early on Saturday, October 11, Keaton was taken by ambulance to the hospital. Sadly, though, she did not make it out alive. The cause of her death is still unknown.
From ‘Annie Hall’ to Hollywood’s Iconic Elder Stateswoman
Keaton was more than just an actor; she was a force for generations to come, with her floppy hats, crisp clothes, and a voice full of love and humor.

Starring in “The Godfather” as Kay Adams, she cemented her legacy with “Annie Hall,” winning an Oscar and starting a sartorial trend that continues to this day.
Her subsequent roles in “The First Wives Club,” “Something’s Gotta Give,” and the “Book Club” movies showcased her ability to depict women with nuance, grace, and bravery.

She took on her mother’s maiden name, Keaton, after being born Diane Hall in Los Angeles in 1946, and she never looked back. She was a unique star because of her genuineness both on and off television.
As they grieve the passing of a woman whose legacy will live on via her movies, her style, and her fierce spirit, Keaton’s family has requested solitude.

A woman who, despite its complexity, inspired us to laugh, cry, and believe in love. Never forgotten, yet gone. Keaton, rest in peace.
