The actress grew up before television audiences, and spent her later years speaking openly about the struggles that existed beyond the screen.

Hayden Panettiere spent nearly her entire life in front of a camera.

Long before audiences knew her as the indestructible cheerleader Claire Bennet on Heroes or the ambitious country singer Juliette Barnes on Nashville, Panettiere was already working as a child performer. What followed was a career that stretched across television, film, voice acting and music, taking her from daytime soap operas to some of the most recognizable roles of her generation.

Panettiere died Aug. 16 in Greenville, South Carolina. She was 36 and would have celebrated her 37th birthday five days later.

Her career in entertainment began before she was old enough to understand what a career was. Panettiere appeared in commercials as a small child before moving into television. She eventually joined the casts of daytime dramas including One Life to Live and Guiding Light, where she played Lizzie Spaulding. Those early years placed her among a relatively small group of performers who essentially grew up while working in the entertainment industry.

By the late 1990s, Panettiere was moving steadily into film. She voiced Dot in Pixar's A Bug's Life in 1998 and later appeared in Remember the Titans, the 2000 football drama starring Denzel Washington. Her performance as Sheryl Yoast, the football-loving daughter of assistant coach Bill Yoast, gave movie audiences an early glimpse of the personality that would later become central to many of her best-known roles.

Other film appearances followed, including Raising Helen, Ice Princess, Bring It On: All or Nothing and I Love You, Beth Cooper.

But television would ultimately make Panettiere a household name.

In 2006, she was cast as Claire Bennet on NBC's Heroes, playing a teenage cheerleader who discovers that she has the ability to rapidly heal from injuries. The series became a major television hit, and Panettiere quickly became one of its most recognizable stars. Her work on the show earned her three Teen Choice Awards and pushed a young performer who had already been working for years into a new level of celebrity.

Several years later, Panettiere took on a very different character.

Beginning in 2012, she starred opposite Connie Britton in the musical drama Nashville. Panettiere played Juliette Barnes, a young country star navigating fame, competition, relationships and personal turmoil. The part allowed Panettiere to combine acting and music, with songs she performed for the series reaching Billboard's country charts.

Her portrayal of Barnes earned Panettiere two Golden Globe nominations and became one of the defining performances of her career.

She also developed a following among horror fans through her portrayal of Kirby Reed in Scream 4. More than a decade later, she returned to the character in Scream VI in 2023, marking a prominent return to the screen after several years away from acting.

Her final screen performance came in the psychological thriller Sleepwalker, released in January 2026, in which she played a grieving mother dealing with disturbing sleepwalking episodes.

A More Personal Chapter

In the later years of her life, Panettiere became increasingly willing to speak publicly about experiences that were far removed from red carpets and television premieres.

She discussed her struggles with alcohol and substance addiction, depression and postpartum depression following the birth of her daughter, Kaya, in 2014. She also spoke about seeking treatment and about the complicated effect that beginning a professional career so young had on her adult life.

Her younger brother, actor Jansen Panettiere, died unexpectedly in February 2023 at 28 from complications associated with an enlarged heart and an aortic valve condition. His death deeply affected Panettiere, who continued to discuss the grief of losing him in interviews during the years that followed.

In May 2026, just three months before her death, Panettiere released the memoir This Is Me: A Reckoning. The book examined her childhood in entertainment as well as addiction, recovery, postpartum depression, family relationships, trauma, motherhood and grief.

During interviews surrounding the book's release, Panettiere said she hoped speaking openly about those experiences could be useful to people facing struggles of their own.

Those conversations became some of her final major public appearances.

Her Death Remains Under Investigation

Emergency responders were called to a residence in Greenville on the afternoon of Aug. 16 after Panettiere was found unresponsive. Paramedics attempted lifesaving measures, including CPR, but she was pronounced dead at the scene.

An autopsy found no signs of trauma, and Greenville police have said the preliminary investigation showed no indication of foul play or suspicious circumstances.

An excerpt from the emergency call referenced responders being dispatched for a reported overdose. That detail has led to widespread reporting and speculation about the circumstances of Panettiere's death. However, authorities have not determined an official cause of death, and the investigation remains open while additional testing is completed.

That distinction is important. Panettiere had publicly discussed addiction during her life, but her history alone does not establish what caused her death.

In the days since her passing, actors, former co-stars and others who worked with Panettiere have shared memories of a performer many of them first knew when she was still a child. Her former Nashville co-star Connie Britton was among those who remembered her publicly, while former fiancé Wladimir Klitschko reflected on the career Panettiere built and the difficult circumstances she faced along the way.

Panettiere is survived by her daughter, Kaya, whom she shared with Klitschko.

Her death brings an unexpectedly early end to a career that lasted approximately three decades. For some viewers, she will remain the young girl from Remember the Titans. For others, she will always be Claire Bennet, Kirby Reed or Juliette Barnes.

Behind all of those characters was a woman who had spent almost her entire life being watched by the public — first as a child actor, then as a television star, and eventually as an adult attempting to speak for herself about what that life had cost her.

At 36, Hayden Panettiere's story ended far earlier than anyone expected. The investigation may eventually provide answers about how she died. Her work, however, already provides a record of the career she built and the many stages of a life lived largely in public.
