Hayden Panettiere, the actress who became a household name playing the indestructible cheerleader Claire Bennet on NBC's Heroes and country music star Juliette Barnes on Nashville, has died at the age of 36. [1]

Her representative confirmed the news in a statement to ABC News: "It is with profound sadness that we share the tragic passing of our beloved Hayden. She was an incredible light and a force of nature who brought immeasurable love and joy to all who knew her — and to the millions who watched her onscreen." [1] The circumstances surrounding her death have not been disclosed. [1]

A Career Built in the Spotlight

Panettiere spent much of her life in front of cameras, transitioning from child actress to leading television star over a career that spanned decades. Beyond her signature television roles, she appeared in films including I Love You, Beth Cooper, Scream 4, and Scream VI, as well as the TV movie Amanda Knox. [1]

Her dual identity as both a dramatic and genre actress gave her an unusually broad fanbase — from viewers who followed her superhero mythology in Heroes to horror enthusiasts who welcomed her into the long-running Scream franchise. [1]

Personal Struggles and a Final Memoir

In the months before her death, Panettiere had stepped into a new chapter of candor. Earlier this year she released This Is Me: A Reckoning, a memoir in which she wrote openly about growing up under public scrutiny as a child star, her struggles with addiction, and her experience with postpartum depression. [1]

Speaking with The Hollywood Reporter ahead of the book's May release, she described the care she took in writing about the people in her life. "I was fiercely protective of people in my writing," she said. "I felt very strongly about my ability to tell my stories and make them entertaining enough to put in a book, without having to drag people through the mud." [1]

She added that she leaned on trusted members of her inner circle during the writing process — and made a point of ensuring her ex-fiancé, Ukrainian heavyweight boxing champion Wladimir Klitschko, would not be blindsided by the book's contents. "I just had to speak my truth — and it's mine alone," she said. [1]

Family Losses and Personal Life

Panettiere's personal life was marked by both deep connection and significant grief. She and Klitschko were in a relationship from 2009 to 2011 and again from 2013 to 2018; together they had a daughter, Kaya, born in 2014. [1]

Her death comes roughly three years after a devastating family loss: her younger brother, actor Jansen Panettiere, died in February 2023 at age 28 from aortic valve complications. [1] Hayden Panettiere was 36 — just eight years older than her brother was when he died.

What to Watch

Authorities and her representatives have not yet released information about the cause or circumstances of her death. Further details are expected as family and representatives make additional statements. Readers following coverage of her memoir, This Is Me: A Reckoning, may find it takes on renewed significance as a final, unfiltered account of her life in her own words.
