Diane Keaton's family has confirmed that the Oscar-winning actress died from pneumonia on October 11. The announcement was made in a statement to a magazine, where the family expressed gratitude for the outpouring of love and support they received following her passing. "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," the statement read.

Keaton, who was 79 years old at the time of her death, was transported to a hospital in Los Angeles after emergency responders arrived at her home. The news of her death shocked fans and colleagues around the world.

Known for her iconic roles in films such as "Annie Hall," "The Godfather" series, and "Father of the Bride," Keaton's career spanned over six decades. She won an Academy Award for her performance in "Annie Hall" and received three additional nominations for her work in "Reds," "Marvin's Room," and "Something's Gotta Give."

Keaton was born Diane Hall in January 1946 in Los Angeles. Although her family was not involved in the film industry, she pursued acting after graduating from Santa Ana College. She made her Broadway debut in the musical "Hair" in 1968 and transitioned to film with her role in "Lovers and Other Strangers."

Her breakthrough came in 1972 when she portrayed Kay Adams Corleone in "The Godfather," a role she reprised in its sequels. Keaton's unique style and memorable performances made her a beloved figure in cinema.

In addition to her film achievements, Keaton was known for her philanthropic efforts. Her family encouraged donations in her memory to local food banks or animal shelters, reflecting her love for animals and support for the unhoused community.

A source close to Keaton mentioned that her health had declined suddenly in recent months, which was unexpected for someone known for her strength and spirit. The source added that her final months were kept private, even from many of her longtime friends.

Keaton is survived by her two younger sisters and her two adopted children, Dexter and Duke. She once remarked, "Motherhood has completely changed me. It’s just about like the most completely humbling experience that I’ve ever had." No public memorials have been announced at this time.
