Sources with direct knowledge tell TMZ ... Hayden passed away earlier on Sunday. We're told she and her on-again, off-again boyfriend Brian Hickerson flew from Los Angeles to the south on Saturday. Sources tell us Brian's family is aware and say "it's a sad situation." "It is with profound sadness that we share the tragic passing of our beloved Hayden. 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," her rep said in a statement to ABC News. Panettiere became a household name as a child actress before landing her breakout role as cheerleader Claire Bennet on NBC's "Heroes."

The late actress also appeared in the beloved "Scream" franchise ... including "Scream 4" and "Scream VI," and lent her voice to the video game "Until Dawn."

Jansen died in 2023 at age 28. Hayden later spoke candidly about the devastating impact of his death and the guilt she carried following his passing. Panettiere was also mom to daughter Kaya, whom she shares with former fiancé Wladimir Klitschko. We last saw Hayden at LaGuardia Airport in May with a friend ahead of her memoir release, keeping it mostly quiet through it all -- no big reveals, no denials ... just one very telling grin.
