Hayden and Jansen grew up in Palisades, NY, in an absolute fairy tale of a home. Last year, the actress told the New York Times that her parents gave her a "great childhood where she was able to attend prom and play sports, though she was always working. "

Hayden Panettiere opened up about her late brother, Jansen Panettiere, for the first time in a new interview. Jansen Panettiere died at the age of 28 in February 2023. TMZ was first to report the news that Jansen died in New York on February 19.

When Hayden Panettiere's younger brother died unexpectedly of an undiagnosed heart condition last year, the actor said it was like losing a part of herself.
