Hayden Leslie Panettiere (/ˌpænᵻˈtɪər/; Italian: [panetˈtjɛːre]); born August 21, 1989) is an American actress, model, singer, and activist. She is known for her roles as cheerleader Claire Bennet on the NBC series Heroes (2006–10), Juliette Barnes in the ABC musical drama series Nashville (since 2012) and Kairi in the video game series Kingdom Hearts.
A native of New York, she first appeared in a commercial at the age of 11 months. She began her acting career by playing Sarah Roberts on One Life to Live (1994–97), and Lizzie Spaulding on Guiding Light (1996–2000), before starring at age 10 as Sheryl Yoast in the Disney feature film Remember the Titans. Other notable roles include her portrayal of the title character in the true crime drama Amanda Knox: Murder on Trial in Italy and Kirby Reed in the slasher film Scream 4. She received two nominations for the Golden Globe Award for Best Supporting Actress – Series, Miniseries or Television Film, for her work on Nashville in 2012 and 2013.
Panettiere was born in and partly raised in Palisades, New York. She is the daughter of Lesley R. Vogel, a former soap opera actress, and Alan Lee "Skip" Panettiere, a fire captain. She has one younger brother, fellow actor Jansen Panettiere. Panettiere has Italian and German ancestry. Her surname means "baker" in Italian (specifically, one who makes bread and bread-related products) and her mother's maiden name means "bird" in Dutch and German. Her mother's family lives in Indiana.
After Panettiere attended South Orangetown Middle School in New York, she was homeschooled from grade nine to the completion of high school.
Panettiere dated her Heroes co-star Milo Ventimiglia from December 2007 to February 2009. She met former heavyweight world champion boxer Wladimir Klitschko in 2009 at the book launch party for mutual acquaintance Diana Jenkins' Room 23 (both appeared in the book), and they soon began dating. Panettiere was ringside for Klitschko's knockout victory over Samuel Peter on September 11, 2010. In May 2011, she announced that they had broken up amicably after two years together. Both cited the long-distance nature of their relationship as the reason, and said they would remain close friends. Panettiere confirmed reports that she and Klitschko had resumed their romantic relationship in an April 2013 interview. In October 2013, she announced her engagement to Klitschko, which had been rumored since the summer. In 2014, Panettiere gave birth to a daughter.
Panettiere followed a vegetarian diet while she starred in Heroes but has since added chicken and fish to her diet, stating that she "didn't respond well" to a vegetarian diet, and she had "low energy".
In 2015, she stated that following the birth of her daughter she experienced post-partum depression. In her September 28 appearance on Live with Kelly and Michael, she said that it's "scary and needs to be talked about". In October, Panettiere voluntarily checked into a facility for treatment, causing her to have to temporarily leave Nashville.
