Hayden Panettiere's Heartbreak: Brother's Death Devastates Actress

Actress Hayden Panettiere experienced profound grief following the death of her younger brother, Jansen Panettiere, in February 2023. Jansen, who was 28, succumbed to aortic valve complications and an undiagnosed enlarged heart. Hayden, who had a deep bond with her only sibling, described his loss as losing half her soul.

The siblings shared a passion for acting, appearing together in the 2004 Disney Channel Original Movie "Tiger Cruise" and reuniting in "The Forger" in 2011. Jansen also had roles in "Robots," "Ice Age: The Meltdown," and "The Walking Dead," among others. As an adult, he found joy in his art, sharing his paintings on Instagram.

Hayden, who was preparing for the premiere of "Scream VI" at the time of Jansen's death, found solace in her past treatment for addiction and mental health. However, the emotional toll of his passing was immense, leading to struggles with agoraphobia, exacerbated by seeing paparazzi photos at his funeral.

She continues to honor Jansen's memory with frequent tributes, most recently posting in September 2025 for what would have been his 31st birthday. Panettiere described him as a remarkable, wise, and pure human being, expressing her enduring love and the belief that they will be reunited.
