Diane Keaton died on Oct. 11 at age 79, according to reports from The New York Times and People.
Her death sent shockwaves across America, especially as just last December, she had released her debut holiday song “First Christmas.” Keaton’s death also came as a surprise to those close to her, with a friend of Keaton telling People, “It was so unexpected, especially for someone with such strength and spirit.”
The source added: “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.”
However, a closer look at Keaton’s final months reveals that she may have quietly been saying her goodbyes and preparing for the end.
In March, Keaton put her home on the market for $29 million. The “Annie Hall” actress, who moonlighted as a house flipper, was not shy about how this was her “dream home,” making this decision a brow raiser. Keaton had completed an extensive, years-long renovation on the property, which she detailed in her 2017 book “The House that Pinterest Built.” Less than two months after listing, Keaton reduced the price to $27.5 million, which may have simply been a routine price adjustment or an attempt to sell the property faster.
Additionally, Keaton began to disappear online. Once an avid Instagram user, Keaton only posted twice this year. Her final post, shared in April, showed her at home with her dog in honor of National Pet Day. Keaton also posted in January, asking followers to donate to a GoFundMe page for domestic workers affected by the Palisades fires.
A look at her past Instagram posting cadence proves her online activity took a massive dip. Up until 2025, Keaton posted multiple times a month on the social media platform. In 2019, she confessed to ET about her frequency on the app.
“It becomes a bad habit,” she said. “It starts to be that thing you check too often. I’m still praying maybe I’ll get a million viewers, but I’ll never be Reese Witherpsoon. What does she have — 15 million? I don’t even understand. I got to calm it down!”
Furthermore, Keaton also stepped away from her daily routine towards the end of her life. A second source, who lived in Keaton’s neighborhood, told People she used to be seen walking her dog regularly. But in the past few months, they stopped seeing her.
“She lived in Brentwood for many years,” the source began. “She loved her neighborhood. 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.”
The source added, “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.”
Details surrounding Keaton’s cause of death have yet to be revealed.
