Hayden Panettiere's Death: Why She Couldn't Leave Ex Brian Hickerson

American actress Hayden Panettiere died suddenly on August 16, 2026, at age 36 in Greenville, South Carolina. Rescue workers reported cardiac arrest and a possible overdose, with authorities currently ruling out foul play. Panettiere had a turbulent relationship with Brian Hickerson, who was convicted of domestic violence in 2020. His half-sister claims Hickerson's charisma kept Panettiere returning, though reports say she hired security to keep him away during her book tour in May. The "Heroes" and "Nashville" star had recently published a memoir about her struggles with addiction and postnatal depression. She is survived by her daughter with former boxer Wladimir Klitschko.
