Diane Keaton’s Family Breaks Silence on Cause of Death

Diane Keaton's family opening up a bit about what happened and how they would like fans to honor her.

What the family said

In a statement shared with People, Keaton's loved ones confirmed she died of pneumonia on October 11 at the age of 79. They thanked everyone for the outpouring of support and, in true Diane Keaton fashion, pointed attention toward causes she cared about.

"We are very grateful for the extraordinary messages of love and support... Diane passed away from pneumonia on October 11."

They also noted her lifelong commitment to animal welfare and to helping unhoused people, suggesting that anyone looking to pay tribute consider donating to a local food bank or an animal shelter. A representative added that there are no further details to share and asked for privacy as the family grieves.

How it unfolded

People also quoted a source close to the family who said Keaton's health declined very suddenly, which made this loss feel especially shocking. According to that insider, she was known for her strength and spirit, and in her final months she kept things very private, spending time only with her closest family.

A quick look back

• Born Diane Hall in Los Angeles in 1946
• Broke out with The Godfather films and became a generational screen presence
• Won the Best Actress Oscar for Annie Hall in 1977
• Starred in The First Wives Club, The Family Stone, and HBO's The Young Pope
• Adopted two children, Dexter and Duke, and chose not to marry

Keaton's career covered decades, genres, and a very specific blend of wit and vulnerability that nobody else could quite copy. If you are looking to do something in her memory, her family suggests a donation to a local food bank or animal shelter. Seems fitting for someone who left such a big mark on and off screen.
