The cause of death of Oscar-winning actress Diane Keaton has reportedly been revealed.

Keaton, 79, died on Oct. 11 of pneumonia, according to People magazine, which cited a statement from the actress' family, which also expressed thanks for "the extraordinary messages of love and support."

Details about Keaton's death were not immediately available when her death was confirmed on Saturday.

At the time, the Los Angeles Fire Department said it responded to a medical call to Keaton's Brentwood home at 8:08 a.m. local time on Saturday and took a patient to the hospital.

Keaton rose to fame in the 1970s with her role as Kay Adams in "The Godfather" films, and, in 1978, she won the Academy Award for best actress for her performance in "Annie Hall."

She is also known for her roles in "Play It Again, Sam," "Baby Boom," "The First Wives Club" and the "Book Club" franchise.

She told ABC News in 2022 that she had been "very fortunate to have many opportunities that came my way."

She said, "What made my life interesting was I had freedom. You know, that I had the opportunity to make my choices with time as it went on."
