LOS ANGELES — The family of renowned Oscar winner Diane Keaton has disclosed the cause of her passing to People Magazine, announcing on Wednesday that the beloved actress succumbed to pneumonia.

In a heartfelt statement shared with the magazine, Keaton’s family expressed their deep appreciation for the outpouring of love and support they’ve received. “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 said.

Keaton, celebrated for her iconic roles in films such as “Annie Hall,” “The Godfather” series, and “Father of the Bride,” passed away on October 11 at the age of 79.

According to reports, emergency services from the Los Angeles Fire Department responded to a call at Keaton’s residence and subsequently transported her to a nearby hospital, where she passed away.

Los Angeles Fire responded to Keaton’s home and transported her to an L.A. area hospital where she died.

No public memorials have been announced yet.

The unexpected news was met with shock around the world. Keaton was the kind of actor who helped make films iconic and timeless, from her “La-dee-da, la-dee-da” phrasing as Annie Hall, bedecked in that necktie, bowler hat, vest and khakis, to her heartbreaking turn as Kay Adams, the woman unfortunate enough to join the Corleone family.

Keaton won her first Oscar for “Annie Hall” and would go on to be nominated three more times, for “Reds,” “Marvin’s Room” and “Something’s Gotta Give.”

In her very Keaton way, upon accepting her Oscar in 1978 she laughed and said, “This is something.”

Keaton was born Diane Hall in January 1946 in Los Angeles, though her family was not part of the film industry she would find herself in. Her mother was a homemaker and photographer, and her father was in real estate and civil engineering.
