Diane Keaton – Death Confirmed at 79, Hoax Debunked, Bio

On October 11, 2025, the entertainment world learned that Diane Keaton, the iconic Oscar-winning actress, had died at her California home. She was 79.

The earlier hoax and the real death are two separate events that have caused considerable public uncertainty.
