Hollywood is mourning the loss of Diane Keaton.

The Oscar-winning actress — known for her roles in Annie Hall, the Godfather trilogy, Father of the Bride, Something’s Gotta Give and The First Wives Club — died on Saturday in California at the age of 79. Her cause of death is not yet available.

Following the news of her death, many of her former co-stars, industry figures and stars took to social media to share tributes.

Robert De Niro shared a statement with The Hollywood Reporter, which reads: “I am very sad to hear of Diane’s passing. I was very fond of her and the news of her leaving us has taken me totally by surprise. I was not expecting her to leave us. She will be missed.  May she rest in peace.”

Bette Midler, who starred alongside Keaton and Goldie Hawn in 1996’s The First Wives Club, took to Instagram to write: “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!”

Additionally, Hawn’s daughter and actress Kate Hudson shared a clip of three women in the film with the caption, “We love you so much Diane.”

Steve Martin, whom she starred alongside in 1991’s Father of the Bride, shared a clip of a 2021 interview she did with Martin Short for Interview magazine, in which Short asks Keaton, “Who’s sexier, me or Steve Martin?,” and Keaton replies, “I mean, you’re both idiots.” Martin captioned the post: “Don’t know who first posted this, but it sums up our delightful relationship with Diane.”

Keaton’s Book Club co-star Candice Bergen said in a statement to THR, “This is a huge loss both personally and for all of us. Diane was a true artist — tremendously gifted and uniquely talented in so many disciplines yet also modest and wonderfully eccentric. I will miss her terribly.” 

Leonardo DiCaprio, who played Keaton’s nephew in Marvin’s Room (where she earned one of her four Oscar noms), posted a tribute on his Instagram Stories. “Diane Keaton was one of a kind. Brilliant, funny, and unapologetically herself,” he wrote alongside a photo of himself and Keaton. “A legend, an icon, and a truly kind human being. I had the honor of working with her at 18. She will be deeply missed.”
