In a devastating turn of events, the legendary actress Diane Keaton has left us too soon at the tender age of 79. Just days after her passing on October 11th, the news of her cause of death has been revealed, leaving fans and friends stunned and heartbroken.

According to a poignant statement from her family, issued to People magazine on Wednesday, Keaton's untimely demise was due to pneumonia. The emotional tribute not only shed light on the late actress's life but also honored her enduring legacy as a Hollywood icon. As the Keaton family expressed their gratitude for the outpouring of love and support, they revealed that any donations in Diane's memory to local food banks or animal shelters would be a fitting tribute to her compassionate spirit.

Over the weekend, the news of Keaton's passing sent shockwaves through Tinseltown, with fellow celebrities and fans alike paying homage to the one-of-a-kind actress. A friend close to Keaton revealed that her health had taken a drastic turn in recent months, leaving everyone who loved her reeling from the sudden loss.

"It was so unexpected, especially for someone with such strength and spirit," the insider shared with People. "In her final months, she was surrounded only by her closest family, who chose to keep things very private. Even longtime friends weren't fully aware of what was happening."

The 911 call that alerted authorities to Keaton's condition paints a harrowing picture of her final moments. Obtained by TMZ, the chilling recording captures the frantic dispatcher calling for emergency services to respond to reports of a "person down" at Keaton's residence around 8 a.m.

Keaton's passing also brings back memories of her tumultuous yet enduring romance with actor Al Pacino, whom she dated from 1971 to 1987. A close friend of the Oscar-winning actor revealed that he harbored a lifelong regret for not marrying Keaton when he had the chance. "Looking back, Al admits the love of his life was Diane, who he's always called 'an amazing woman,'" a confidante shared with The Scholarly Note.

The friend continued, "I know he will forever regret he didn't make his move when he had the chance." Pacino, now 85, seems to have finally accepted that it is too late for a do-over. Keaton's death has sparked a wave of tributes from Hollywood stalwarts, including Leonardo DiCaprio, Bette Midler, and Francis Ford Coppola.

DiCaprio eulogized Keaton as "brilliant, funny, and unapologetically herself," adding that "she will be deeply missed." Midler praised the late actress for being "hilarious, a complete original, and completely without guile... What you saw was who she was…oh, la, lala!"

Sager added, 'She was down there for a while, and when she came back, I was kind of stunned by how much weight she'd lost'; seen in 2018 in L.A.

Coppola shared on Instagram that Keaton's passing has left him speechless: "Words can't express the wonder and talent of Diane Keaton. Endlessly intelligent, so beautiful... Everything about Diane was creativity personified."

Keaton's illustrious career spanned decades, with some of her most iconic performances taking place in the 1970s. Her collaboration with Woody Allen on Annie Hall (1977) earned her the Best Actress in a Leading Role award at the Oscars and cemented her status as a Hollywood legend.

However, it seems that not everyone was aware of Keaton's fragile health before her passing. Songwriter Carole Bayer Sager revealed to People that she had seen Keaton just two or three weeks prior to her death, only to be shocked by the actress's alarming weight loss. "I saw her fairly recently at Jack Nicholson's birthday party, and it was good to see her there," Ed Begley Jr., who attended the bash with Keaton, shared.

Begley continued, "She's a wonderful actress, a wonderful lady. I played her brother in an HBO film called Running Mates with Ed Harris. So I'm glad I knew her these many years." Begley also expressed his admiration for Keaton's relationship with Jack Nicholson, stating that they both loved each other dearly.

As the news of Keaton's passing continues to reverberate through Tinseltown, fans and friends alike are left to ponder what could have been. What secrets lay hidden in Keaton's final months? How did her beloved family cope with her sudden decline? The enigmatic actress leaves behind a legacy that will continue to inspire generations of performers to come.

In the words of Diane Keaton herself, "Everything I do is either going to be fabulous or a disaster." Her untimely passing may have been a disaster for those who loved her, but it has left an indelible mark on Hollywood's collective heart. As the curtain falls on one of our most beloved stars, we remember the love, laughter, and tears she brought to our lives – and continue to cherish her timeless legacy.
