Oscar-winning 'The Godfather' and 'Annie Hall' star Diane Keaton dead at age of 79

Actress Diane Keaton, known for her Oscar-winning performance in 1977's "Annie Hall" and her role in "The Godfather" films, has died at age 79, People magazine reported Saturday.

Details were not immediately available and Keaton's loved ones have asked for privacy, a family spokesperson told People, which confirmed that the actress died in California.

Keaton was a frequent collaborator of director Woody Allen, portraying the titular character in "Annie Hall," the charming girlfriend of Allen's comic Alvy Singer.

The film also garnered Oscars for best picture, best director and best original screenplay, cementing Keaton's place as one of the industry's top actresses and an offbeat style icon as well.

The actress made her mark co-starring in eight Allen movies, from "Play in Again Sam" (1972) to "Manhattan" (1979) and "Manhattan Murder Mystery" (1993).

As the Hollywood sexual harassment scandals detonated in late 2017, cascading from producer Harvey Weinstein to heavyweight actors like Kevin Spacey, old accusations of child sex abuse against Allen by his adoptive daughter Dylan resurfaced.

"Woody Allen is my friend and I continue to believe him," Keaton tweeted in January 2018.

A BAFTA and Golden Globe winner, Keaton scored Oscar nominations three other times for best actress, for "Reds," "Marvin's Room" and "Something's Gotta Give."

In "The Godfather" films, she played Kay Adams, the girlfriend and eventual wife of Al Pacino's Michael Corleone.

Late in her career, Keaton starred in two movies about aging women: "Book Club" (2018), with its message that love has no age, and "Poms" (2019).

"Poms" is the story of Martha, a terminally ill woman who moves to a retirement community to die, but winds up forming a cheerleading squad made up of female senior citizens.

As for aging, Keaton said in a 2019 interview with AFP that life actually got easier.

"I think so, because what have you got to lose? It's like it's the truth. That's what it is. You face it, we talk about it," she said.

Born Diane Hall in Los Angeles on January 5, 1946, Keaton was romantically involved with Allen, Pacino and Warren Beatty, but never married.

"Most people in the movies get married at some point and then they divorce. But I've never even got married. I am (a) failure," she joked in the 2019 interview.

Did she regret it? "I don't think about it a lot but I'm aware of the fact that I'm unusual in that regard, and maybe I did miss out on something -- but then, nobody can have everything, right?"

She is survived by her two children, Dexter and Duke.
