The American actress Diane Keaton, best known for roles in Annie Hall, The Godfather, and Something's Gotta Give, has died at the age of 79, according to US magazine People.
Ms Keaton died in her native California, and her loved ones have asked for privacy, a family spokesperson told the outlet.
Dori Rath, a producer and friend of Ms Keaton, also confirmed her passing to CBS News and The New York Times.
The actress shot to fame in the 1970s with her role as Kay Adams in The Godfather trilogy, as well as her collaborations with Woody Allen.
She won a Best Actress Oscar for Mr Allen's influential film Annie Hall and became associated with the title character's menswear-centric wardrobe.
She made a total of eight films with Woody Allen, including 1979's Manhattan.
Diane Keaton was also a BAFTA winner for Annie Hall and a Golden Globe winner for Annie Hall and Something's Gotta Give.
Her many beloved films included Baby Boom, The First Wives Club, Father of the Bride, The Family Stone, and the Book Club movies. In 2017, she starred opposite Irish actor Brendan Gleeson in the comedy-drama Hampstead.
She was also nominated for Oscars for her roles in Something's Gotta Give, Marvin's Room, and Reds.
As a director, her credits included the films Heaven and Hanging Up, the series China Beach and Twin Peaks, and the promo videos for the Belinda Carlisle hits Heaven Is a Place on Earth and I Get Weak.
Paying tribute on Instagram, Belinda Carlisle said Diane Keaton "was such a talent and a big part of my career".
Alongside broken-heart emojis, the singer wrote: "She was kind and eccentric and I was blessed to know her. This is such a big loss…"
Diane Keaton's First Wives Club co-star Bette Midler wrote on Instagram: "The brilliant, beautiful, extraordinary Diane Keaton has died. I cannot tell you how unbearably sad this makes me.
"She was hilarious, a complete original, and completely without guile, or any of the competitiveness one would have expected from such a star. What you saw was who she was ... oh, la, lala!"
Born Diane Hall in Los Angeles on 5 January, 1946, Diane Keaton was romantically involved with Woody Allen, Al Pacino, and Warren Beatty, but she never married.
She is survived by her two children, Dexter and Duke.
