Hayden Panettiere, the former child star who grew up before audiences and became best known for her roles in “Heroes,” “Nashville” and “Remember the Titans,” has died. She was 36.

Panettiere died Sunday, Aug. 16, in Greenville, South Carolina, after she was found unresponsive at an apartment complex. Emergency personnel attempted life-saving measures, but she was pronounced dead at the scene. Authorities said there were no signs of foul play or suspicious circumstances. A cause of death has not yet been announced.

Her father remembered her as someone whose presence reached far beyond the screen.

“It is with profound sadness that we share the tragic passing of our beloved Hayden,” he said in a statement. “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.”

For many of those millions, Panettiere seemed to have been part of Hollywood for nearly her entire life. Born Aug. 21, 1989, she began appearing in commercials as a young child before landing roles on “One Life to Live” and “Guiding Light.” Her early film work included “A Bug’s Life,” “Remember the Titans,” “Raising Helen” and “Ice Princess.”

Her breakthrough came in 2006 when she was cast as Claire Bennet, the seemingly indestructible cheerleader at the center of NBC’s “Heroes.” The series became a cultural phenomenon, and its famous line, “Save the cheerleader, save the world,” helped turn Panettiere into one of television’s most recognizable young stars.

She found another defining role as troubled country singer Juliette Barnes on “Nashville.” Panettiere performed her own music on the series, earned two Golden Globe nominations and placed multiple songs on Billboard’s country charts. She later returned to another fan-favorite role, Kirby Reed, in the “Scream” franchise.

But Panettiere’s life away from the cameras was often far more difficult than her Hollywood success suggested. She spoke candidly about alcoholism, substance abuse, postpartum depression and the pressures of growing up famous. Earlier this year, she released her memoir, “This Is Me: A Reckoning,” offering a deeply personal account of her struggles, relationships, recovery and efforts to rebuild her life.

“I put a lot of work into myself, and I had to be willing to be incredibly honest,” she told PEOPLE in 2022. “There were a lot of ups and downs, but I don’t regret even the ugliest things that have happened to me.”

Panettiere also endured a devastating personal loss in 2023 when her younger brother and only sibling, Jansen Panettiere, died at 28 from complications related to an enlarged heart. She later described the depth of that grief, saying, “When I lost him, I felt like I lost half of my soul.”

She was also a mother to 11-year-old daughter Kaya, whom she shared with former fiancé and Ukrainian boxing champion Wladimir Klitschko. Panettiere had spoken openly about the painful decision for Kaya to live full-time with her father while she struggled with addiction and her mental health, pushing back against the suggestion that she had simply walked away from her daughter.

Through those struggles, Panettiere increasingly allowed the public to see the person behind the celebrity — someone who was still trying to heal, grow and make sense of a life lived largely in the spotlight.

In one of her final interviews, she offered a reflection that now carries added weight.

“I’m a work in progress — we all are,” Panettiere said. “I take each day as it comes. I’m doing the work, and I’m doing my best.”

Panettiere would have turned 37 on Friday. She leaves behind her daughter, her parents and a career spanning more than three decades. For the generations of viewers who watched her grow from a precocious child performer into one of television’s most familiar faces, she will also be remembered for something increasingly rare in Hollywood: her willingness to let people see not only her successes, but also the struggles behind them.
