is an American actress and singer. She first developed professional prominence at the age of eleven with her portrayal of Sheryl Yoast in Disney's Remember the Titans, although for half of her life immediately before that, Panettiere had held roles in each of two soap operas. She portrayed Sarah Roberts on One Life to Live from 1994-1997, and Lizzie Spaulding on Guiding Light from 1996-2000. Panettiere reached a wider audience with her starring role as Claire Bennet on the 2006 NBC television series Heroes.
Panettiere was born and partly raised in Palisades, Rockland County, New York, the daughter of Lesley R. Vogel, a former soap opera actress, and Alan L. "Skip" Panettiere, a fire department lieutenant. She has one younger brother, fellow actor Jansen Panettiere.
Panettiere attended South Orangetown Middle School in New York, but then she earned her education from the 8th grade level through high school at home. Although she has expressed some interest in "continuing to learn," Panettiere has postponed higher education in favor of an acting career,
In 2006, Panettiere began dating Stephen Colletti, the former Laguna Beach: The Real Orange County, star. The couple broke up in September 2007. In December 2007, it was widely reported that she was dating her Heroes co-star Milo Ventimiglia, though Panettiere denied these reports in an interview with GQ. These reports continued through the early part of 2008, and several sources had reported that she asked Ventimiglia to move in with her. In April 2008, during an interview on the BBC's The Chris Moyles Show to promote the second season of Heroes, Ventimiglia confirmed that he was dating Panettiere. They ended their relationship in February 2009.
