Hollywood star Diane Keaton died of pneumonia, her family says.
The actor known for The Godfather, Annie Hall and Father Of The Bride died on Saturday at the age of 79.
"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 family said in a statement to US media.
"She loved her animals and she was steadfast in her support of the unhoused community, so any donations in her memory to a local food bank or an animal shelter would be a wonderful and much appreciated tribute to her."
Pneumonia is an inflammation of the lungs and can make people seriously ill, especially those in their 60s and older, and people who have a heart or lung condition.
Keaton had a long career as a film actor, making her debut in 1970 with Lovers and Other Strangers.
She made her big break in 1972 after playing Kay, the girlfriend and then wife of Al Pacino's Michael Corleone in Francis Ford Coppola's The Godfather, a role she reprised in 1974's The Godfather Part II and 1990's The Godfather Part III.
Keaton went on to appear in The Family Stone, The Book Club movies and more recently in Summer Camp and Arthur's Whisky in 2024.
Filmmaker Nancy Meyers, who Keaton worked with on a number of films including Baby Boom (1988), Father Of The Bride (1992) and Something's Gotta Give (2004), paid tribute to the star in a post on Instagram
"She was fearless, she was like nobody ever, she was born to be a movie star, her laugh could make your day and for me, knowing her and working with her - changed my life. Thank you Di. I'll miss you forever," she said.
Following the news of her death, Goldie Hawn and Bette Midler, who starred alongside Keaton in 1996's The First Wives Club, about three women whose husbands had left them for younger women, also paid tribute to their co-star.
Coppola also paid tribute on Instagram and said: "Words can't express the wonder and talent of Diane Keaton. Endlessly intelligent, so beautiful."
Keaton was nominated for Oscars for her roles in Something's Gotta Give, Marvin's Room and Reds, in which she starred opposite Warren Beatty.
For a large part of her career she collaborated with Woody Allen, her one-time boyfriend, including on Annie Hall for which she won the Oscar for best actress and has since become associated with the title character's menswear-centric wardrobe.
In 1996, Keaton adopted a daughter, Dexter, and a son, Duke, four years later, however, never married.
