For millions who grew up watching her on television and the big screen, Hayden Panettiere seemed to possess an unmistakable spark.
From the fearless cheerleader who could not be killed in Heroes to the troubled country music star fighting to hold herself together in Nashville, Panettiere built a career playing women who survived impossible circumstances.
Now, Hollywood is mourning the actress whose own life was marked by extraordinary success, painful struggles and an openness about the battles she endured away from the cameras.
Panettiere has died at the age of 36, her representative confirmed to ABC News. The cause of her death has not been publicly disclosed.
Her death came just days before what would have been her 37th birthday on August 21.
Her father, Skip Panettiere, described his daughter as an “incredible light” and “a force of nature,” saying she brought tremendous joy to the people who loved her and to audiences around the world. The family has asked for privacy as they grieve.
A childhood spent in front of the camera
Panettiere’s relationship with show business began almost before she could walk.
Born on August 21, 1989, in New York, she entered the entertainment industry as a baby and spent much of her childhood acting in commercials, television programs and movies.
She gradually became one of Hollywood’s most recognizable young performers, appearing in films such as Remember the Titans, Raising Helen and Ice Princess.
But it was television that transformed her into an international star.
As Claire Bennet in NBC’s Heroes, Panettiere became one of the faces of the superhero phenomenon that swept television in the late 2000s.
Years later, she showed audiences an entirely different side of herself as Juliette Barnes in Nashville.
The ambitious, complicated and emotionally wounded country singer became one of Panettiere’s defining performances, earning her two Golden Globe nominations.
She also became a familiar face to horror audiences as Kirby Reed in the Scream franchise, appearing in Scream 4 before eventually returning to the character years later.
Behind the fame was a much harder story
The brightness Panettiere projected onscreen often hid a far more difficult reality.
As she grew older, the actress increasingly chose to speak publicly about the struggles that came with growing up in Hollywood.
She discussed addiction, alcoholism, postpartum depression and the emotional toll of fame, describing periods when her personal life became overwhelming.
In a 2022 interview with Good Morning America, Panettiere spoke about trying to understand where her alcoholism ended and her postpartum depression began, acknowledging that she had pushed herself to the point of exhaustion.
Rather than erase those chapters from her story, she eventually confronted them publicly.
Earlier this year, Panettiere released her memoir, This Is Me: A Reckoning, an intensely personal account of childhood stardom, addiction, recovery, motherhood, abusive relationships, trauma and grief.
It was the story of someone who had spent most of her life being watched—and who finally wanted the world to understand what had been happening when the cameras were gone.
A mother, a sister and a woman carrying grief
Away from Hollywood, Panettiere was also a mother.
She welcomed daughter Kaya in 2014 with former fiancé and heavyweight boxing champion Wladimir Klitschko.
Motherhood became intertwined with some of the most difficult years of her life as she confronted postpartum depression and addiction, experiences she would later discuss with unusual candor.
Then came another devastating loss.
In February 2023, her younger brother, actor and artist Jansen Panettiere, died at just 28 from complications involving an enlarged heart and an aortic valve condition.
His death left a wound Panettiere admitted she did not expect would ever fully heal.
The siblings had grown up together in the entertainment industry, and Panettiere later spoke about carrying the grief of losing him even as she attempted to rebuild her own life.
More than the characters she played
Panettiere’s career will inevitably be remembered through iconic roles.
For one generation, she will always be Claire Bennet—the cheerleader whose extraordinary ability to survive helped define Heroes.
For another, she will remain Juliette Barnes, singing through heartbreak, ambition and self-destruction in Nashville.
Others will remember the spirited little girl from Remember the Titans, the skating drama of Ice Princess or the fearless Kirby Reed staring down Ghostface in Scream.
But the final years of Panettiere’s public life revealed something beyond the actress audiences knew.
She became increasingly willing to show the person underneath the celebrity—the woman who had stumbled, suffered, grieved and fought to recover.
Just months before her death, she was sharing that story in her memoir, turning deeply painful experiences into something she hoped might help people facing struggles of their own.
At 36, that story has ended far too soon.
Hayden Panettiere spent nearly her entire life in front of an audience. She made people laugh, cry, cheer and sing along. Yet perhaps one of the most enduring parts of her legacy will be the courage with which she eventually allowed people to see not only the star she had been expected to become, but the imperfect and vulnerable human being behind her.
She leaves behind her daughter, her family, decades of performances—and generations of viewers who watched her grow up alongside them.
For those fans, the characters will remain.
But the light behind them is gone.
