American actress Hayden Panettiere, known for her roles in TV shows such as Nashville and Heroes, has died at the age of 36, US media outlets including ABC News reported, citing a statement from her father.

“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,” ABC quoted her father, Alan ‘Skip’ Panettiere, in the statement. The cause of her death was not reported by ABC. Her agency did not immediately respond to a request for comment from Reuters.

A former child actress, Panettiere gained widespread recognition voicing Dot, the young princess ant in Pixar’s 1998 animated hit A Bug’s Life. Her work on the film’s read-along album earned a Grammy nomination for Best Spoken Word Album for Children.

She shot to fame playing the high school cheerleader with superpowers, Claire Bennet, on NBC’s serialised hit Heroes, which debuted in 2006. Panettiere earned two Golden Globe nominations, in 2013 and 2014, for Best Supporting Actress in a Television Series, Limited Series or Motion Picture Made for Television for her role as Juliette Barnes in the musical drama Nashville.
