Before she became the indestructible cheerleader from NBC's latest hit series "Heroes," Hayden Panettiere already had a number of successes. She began her acting career at just eleven months old with a Playskool commercial, and since then, she's had 50 commercial appearances, with Neutrogena as her latest.

She started her TV acting career at age 4 in the soap "One Life to Live" and she was also part of "Guiding Light" cast. Other T.V. credits include roles in "Ally McBeal" and "Malcolm in the Middle." She also lent her voice to Pixar's "A Bug's Life," and the Playstation 2 game "Kingdom Hearts." Her film credits include "Remember the Titans," "Joe Somebody," and "Raising Helen." She'll be part of the 2008 film "Fireflies in the Garden" and her debut album will also be released that year.
