Diane Keaton's health 'declined suddenly' in the months before she died

Diane Keaton's health reportedly "declined very suddenly" in the months before she died.

The Oscar-winning actress' passing at the age of 79 was announced on Saturday (11.10.25) and while no details have been released about the circumstances surrounding her death, insiders admitted it was "unexpected" because she had confided in so few people.

A source told People magazine: “She declined very suddenly, which was heartbreaking for everyone who loved her.

“It was so unexpected, especially for someone with such strength and spirit.

"In her final months, she was surrounded only by her closest family, who chose to keep things very private. Even longtime friends weren’t fully aware of what was happening.”

In March, Diane put her "dream home" in Brentwood, California, up for sale, despite previously vowing to stay there forever, and she was no longer regularly seen in the area walking her dogs.

Another source said: "She lived in Brentwood for many years.

"She loved her neighbourhood. Up until just a few months ago, she'd walk her dog every day. She was usually dressed the same, with a hat and her signature sunglasses regardless of the weather.

"She was always very nice, funny and chatty. She'd talk to her dog like he was a person. She was eccentric and had this old-school Hollywood aura. She was very, very special."
