Diane Keaton’s cause of death has officially been confirmed.
Keaton’s family shared in a statement to People on Wednesday, October 15, that the Oscar-winner died of pneumonia on Saturday, October 11.
“The Keaton family are very grateful for the extraordinary messages of love and support they have received these past few days on behalf of their beloved Diane, who passed away from pneumonia on October 11,” the statement read.
Keaton’s family also detailed more about the actress’ incredible life, telling the outlet, “She loved her animals and she was steadfast in her support of the unhoused community, so any donations in her memory to a local food bank or an animal shelter would be a wonderful and much appreciated tribute to her.”
Us Weekly reached out for comment from Keaton’s representatives.
A spokesperson for the actress confirmed on Saturday, October 11, that she’d died at age 79, though no further details were initially revealed. Her family — which includes daughter Dexter and son Duke — simply “asked for privacy” as they grieved the actress.
A friend of Keaton’s later told People that her heath “declined very suddenly” in the final months of her life adding that the actress had chosen to withdraw from public life in order to spend time strictly with her “very closest family.” While Keaton was reportedly often seen walking her dog Reggie in her neighborhood, those sightings stopped shortly before her death.
Keaton was in the process of trying to sell her 9,200 square foot home in Los Angeles’ Sullivan Canyon neighborhood, despite documenting its ground-up remodeling in her 2017 book The House That Pinterest Built. While she initially listed the property for $28.9 million, she swiftly cut $1.4 million off the asking price in March in hopes of selling it quicker.
Keaton’s final Instagram post was made in collaboration with Hudson Grace, the home decor company which sold her collection, for National Pet Day in April and featured her beloved golden retriever, Reggie, modeling some products from her line.
“Proof our pets have great taste too,” she wrote at the time. “Happy National Pet Day from HG & Diane Keaton.”
