The family of Looking for Mr. Goodbar star Diane Keaton has spoken out, revealing the cause of her death and sharing how they hope the world will remember her. Shock rippled across social media after the news of her passing. Fans and followers reacted with grief, surprise, and disbelief.

One commenter wrote, “What!! Omg, what a horrible thing! I wasn’t expecting that. So sad.” Another asked, “Was it not skin cancer?” Others expressed heartbreak, confusion, and concern over the news.

Cause of Death Confirmed

On October 15, 2025, the Keaton family confirmed to People that she died from pneumonia on October 11. They expressed gratitude for the outpouring of love and support:

“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.”

The family encouraged fans to honor her memory through kindness: donations to food banks or animal shelters would reflect her lifelong love of animals and commitment to helping the unhoused.

A Friend’s Heartbreaking Account

Longtime friend and Oscar-winning songwriter Carole Bayer Sager recalled her final visit with Keaton, just weeks before her death at 79. “I saw her two or three weeks ago, and she was very thin. She had lost so much weight,” Sager said, describing the actress’s frail appearance with sorrow.

Keaton had spent time in Palm Springs after her home suffered damage in January wildfires. Returning from there, she appeared dramatically thinner, leaving friends shocked. Despite declining health, Sager noted, Keaton remained a creative light, photographing everything she saw and staying fully engaged in artistic pursuits.

Creative Spirit to the End

Even in her last months, Keaton poured energy into creativity. She co-wrote her solo single, First Christmas, in 2024, approaching the project with enthusiasm and emotional honesty. Sager recalled, “She was almost childlike about it… she was so authentic when she sang it.”

Her iconic fashion sense — floppy hats, oversized jackets, baggy pants — remained ever-present. Sager added, “She went to the movies always dressed like she was about to shoot another scene for ‘Annie Hall.’ She was a fashion icon of her own making.”

Health Struggles Across a Lifetime

Keaton faced health battles long before her final months. Diagnosed with basal cell carcinoma at 21 and later with squamous cell carcinoma, she endured multiple surgeries. She became a vocal advocate for sun safety, partnering with L’Oréal Paris in 2006 to promote sunblock awareness.

She also privately struggled with bulimia, triggered at age 20 during preparation for a Broadway role. In interviews, she described consuming thousands of calories only to purge afterward, later seeking therapy and committing to recovery.

A Life of Resilience and Privacy

In her final months, Keaton retreated to be with close family, keeping her declining health private. Friends described her passing as sudden and unexpected, highlighting her strength and dignity. Despite this, she remained creative, kind, and inspiring until the end.

Hollywood Icon and Cultural Force

Diane Keaton, born Diane Hall in Los Angeles in 1946, adopted her mother’s maiden name and built a career marked by authenticity and charm. From The Godfather to Annie Hall, she won an Oscar and influenced fashion trends. Later roles in The First Wives Club, Something’s Gotta Give, and the Book Club series showcased her depth and charisma.

Her floppy hats, sharp suits, and signature wit made her a generational icon. But beyond her roles, she inspired millions through honesty about her struggles, advocacy, and creative spirit.

A Lasting Legacy

Keaton’s family has requested privacy during their mourning. Her legacy endures through her films, fashion, humanitarian work, and courage in facing personal battles. Diane Keaton made us laugh, cry, and believe in love — even when it was complicated. She may be gone, but she will never be forgotten.

RIP, Diane Keaton.
