Hayden Panettiere, the actress who became a household name through her roles as a cheerleader in Heroes and a country singer in Nashville and who was open about her struggles with addiction and mental health throughout her adult life, has died at 36.
Her father, Skip Panettiere, confirmed her death in a statement to ABC News on Aug. 16. He described her as an incredible light and a force of nature who brought immeasurable love and joy to those who knew her and to the millions who watched her work on screen.
The cause of her death has not been disclosed. She is survived by an 11-year-old daughter whom she shared with former partner Wladimir Klitschko, a sports scientist and former professional boxer.
Her career
Panettiere began working as a child actress and built a career that spanned more than two decades across television, film and voice work. Her most recognizable roles came in two long-running television series.
Panettiere played Claire Bennet, a high school cheerleader with a power of regeneration, in Heroes, the science fiction series that ran from 2006 through 2010 and drew a large and devoted audience in its early seasons. The role established the combination of emotional vulnerability and physical toughness that characterized her best performances.
Panettiere later played Juliette Barnes, a complicated and commercially successful country music star navigating fame and personal crisis, in Nashville, the drama that aired from 2012 through 2018. The role allowed her to bring her own singing voice to the performance and drew critical praise for its nuance.
Her other credits included providing the voice of Dot in the Pixar film A Bug’s Life, appearing in the football drama Remember the Titans and appearing in Scream VI, released in 2023.
Her openness about personal struggles
Away from the camera, Panettiere was candid throughout her career about the difficulties she faced. She spoke publicly about postpartum depression following the birth of her daughter in 2014 and brought attention to an experience that many new mothers feel pressure to conceal. She was later open about her struggles with alcohol addiction and depression in more direct terms.
That openness placed her among a generation of performers who have used their public visibility to reduce the stigma around mental health treatment and addiction recovery, and it was a meaningful aspect of who she was to those who followed her work closely.
What she leaves behind
Panettiere was 36 years old at the time of her death, a fact that makes the loss feel particularly acute. Her daughter, who is 11, will grow up with her mother’s presence on screen available to her in a way that previous generations did not have, which offers a small but real form of continuity.
The statement from her father described her as a force of nature, which those who watched her work across Heroes and Nashville would recognize as accurate. She was capable of bringing something genuinely alive to characters who could easily have been reduced to their surface characteristics, and that quality is present in the record she leaves behind.
