Diane Keaton's cause of death has reportedly been released days after news of her death became public.

The 79-year-old Hollywood staple died Oct. 11 from pneumonia, her family said in a statement to People magazine on Oct. 15.

"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 to People magazine read.

"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."

Adults 65 years and older are at higher risk of contracting pneumonia, which infects the lungs, due to other chronic health conditions and because immune systems typically get weaker with age.
