The Los Angeles Fire Department confirmed to PEOPLE magazine that emergency responders were called to Keaton’s home at 8:08 a.m. local time and transported a 79-year-old woman to a nearby hospital. The cause of death has not yet been disclosed.

“There are no further details available at this time, and her family has asked for privacy in this moment of great sadness,” a spokesperson told PEOPLE.

Born in Los Angeles in 1946, Keaton rose to prominence in the late 1960s and 1970s with her sharp comedic timing and unconventional screen presence. She gained international fame for portraying Kay Adams-Corleone in Francis Ford Coppola’s The Godfather trilogy, a role that remains among her most memorable.

Keaton’s long association with director Woody Allen led to several acclaimed performances, including her Oscar-winning turn as the neurotic yet endearing title character in Annie Hall (1977), which earned her the Academy Award for Best Actress.

Her versatile career spanned over five decades, with standout roles in films such as The First Wives Club (1996), Something’s Gotta Give (2003), and the Book Club series. In 2003’s Something’s Gotta Give, where she starred opposite Jack Nicholson, Keaton earned critical acclaim and box office success, as the film grossed over $266 million worldwide.

In 2024, she appeared alongside Eugene Levy and Kathy Bates in the comedy Summer Camp, marking one of her final screen appearances.

Following news of her death, tributes poured in from across Hollywood.

Actor Leonardo DiCaprio, who worked with Keaton early in his career, shared a throwback image on Instagram, writing: “Diane Keaton was one of a kind — brilliant, funny, and unapologetically herself. A legend, an icon, and a truly kind human being. She will be deeply missed.”

Her Book Club co-star Jane Fonda wrote: “It’s hard to believe or accept that Diane has passed. She was a spark of life and light — limitlessly creative, endlessly curious, and always uniquely herself.”

Actor Michael Douglas, who starred with her in And So It Goes, called her passing “a heartbreaking loss of one of the greatest icons in our industry.”
