Keaton appeared in many movies throughout her career, including The First Wives Club, Book Club, Annie Hall, Something's Gotta Give and so much more.
She told People in 2019, "I don't know anything, and I haven't learned. Getting older hasn't made me wiser. Without acting I would have been a misfit."
Diane Keaton previously dated Warren Beatty.
Keaton, who adopted two kids: Dexter and Duke, never tied the knot but was linked to Al Pacino, Warren Beatty and Woody Allen, among others, said it would not "have been a good idea for me to have married."
"I'm really glad I didn't, and I'm sure they're happy about it, too," she added about her famous exes.
She also spoke about her stance on marriage. "I remember one day in high school, this guy came up to me and said, 'One day you're going to make a good wife,'" she recalled. "And I thought, 'I don't want to be a wife. No.'"
When asked about her dating life in 2023, she insisted she's better off on her own.
"I don't date," she told AARP The Magazine in 2023. "I don't remember anyone calling me, going, 'This is So-and-So, I'd like to take you out.' They don't happen. Of course not."
