Diane Ladd died on November 3, 2025, at age 89, at her home in Ojai, California, with her daughter Laura Dern by her side. While initial reports varied on the exact cause, public statements did not immediately disclose a definitive medical cause of death. In the years prior, Ladd had been open about suffering from a serious lung condition, idiopathic pulmonary fibrosis (IPF), which has been associated with respiratory decline. However, the family and representatives did not attribute her passing to IPF in the public announcements, so the official cause was not confirmed at the time of the news releases. If you’d like, I can gather the latest statements from family representatives or reputable outlets for the most up-to-date clarification.
