Keaton’s First Wives Club co-star Bette Midler is among the first celebrities to pay tribute, calling the actress “beautiful” and “extraordinary,” and telling fans: “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,” Midler wrote.

Keaton’s acting career spanned almost 60 years, but her Hollywood breakthrough came with a pivotal role in Francis Ford Coppola’s The Godfather in 1972.

She was a frequent collaborator with director Woody Allen, and her star turn in their fourth film together, Annie Hall (1977), earned her an Academy Award for Best Actress.

Keaton’s film career continued to flourish through the decades with beloved hits including Father of the Bride, The First Wives Club, Something’s Gotta Give, The Family Stone, and Book Club.
