Diane Keaton<\/a> died on Oct. 11 at age 79, according to reports from The New York Times<\/a> and People<\/a>.<\/p>\n Her death sent shockwaves across America, especially as just last December, she had released her debut holiday song \u201cFirst Christmas.\u201d<\/a> Keaton\u2019s death also came as a surprise to those close to her, with a friend of Keaton telling People<\/a>, \u201cIt was so unexpected, especially for someone with such strength and spirit.\u201d<\/p>\n The source added: \u201cIn her final months, she was surrounded only by her closest family, who chose to keep things very private. Even longtime friends weren\u2019t fully aware of what was happening.\u201d<\/p>\n However, a closer look at Keaton\u2019s final months reveals that she may have quietly been saying her goodbyes and preparing for the end.<\/p>\n In March, Keaton put her home on the market for $29 million. The \u201cAnnie Hall\u201d actress, who moonlighted as a house flipper, was not shy about how this was her \u201cdream home,\u201d making this decision a brow raiser. Keaton had completed an extensive, years-long renovation on the property, which she detailed in her 2017 book \u201cThe House that Pinterest Built.\u201d<\/a> 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. <\/p>\n Additionally, Keaton began to disappear online. Once an avid Instagram user, Keaton only posted twice this year. Her final post<\/a>, shared in April, showed her at home with her dog in honor of National Pet Day. Keaton also posted<\/a> in January, asking followers to donate to a GoFundMe page for domestic workers affected by the Palisades fires.<\/p>\n 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<\/a> about her frequency on the app.<\/p>\n \u201cIt becomes a bad habit,\u201d she said. \u201cIt starts to be that thing you check too often. I\u2019m still praying maybe I\u2019ll get a million viewers, but I\u2019ll never be Reese Witherpsoon. What does she have — 15 million? I don\u2019t even understand. I got to calm it down!\u201d<\/p>\n Furthermore, Keaton also stepped away from her daily routine towards the end of her life. A second source, who lived in Keaton\u2019s neighborhood, told People she used to be seen walking her dog regularly. But in the past few months, they stopped seeing her.<\/p>\n \u201cShe lived in Brentwood for many years,\u201d the source began. \u201cShe loved her neighborhood. Up until just a few months ago, she\u2019d walk her dog every day. She was usually dressed the same, with a hat and her signature sunglasses regardless of the weather.\u201d<\/p>\n The source added, \u201cShe was always very nice, funny and chatty. She\u2019d talk to her dog like he was a person. She was eccentric and had this old-school Hollywood aura. She was very, very special.\u201d <\/p>\n Details surrounding Keaton\u2019s cause of death have yet to be revealed.<\/p>\n<\/div>\n If you purchase a product or register for an account through a link on our site, we may receive compensation.
