Hayden Panettiere Debuts Hot New Bangs at 'Letterman'

Hayden Panettiere shows off her bangin’ new hairstyle while heading into the Ed Sullivan Theatre for her appearance on The Late Show with David Letterman on Wednesday (August 28) in New York City.

It was just announced that the 24-year-old Nashville actress is being given the Futures Award by the Environmental Media Association at their annual gala this fall.

The award recognizes younger entertainers for their potential to be environmental activists. Hayden, who is active with the Whaleman Foundation, says she is excited to talk about working with the organization and “using my voice to protect our oceans and their amazing inhabitants.”

FYI: Hayden is wearing an Alexander McQueen dress and Saint Laurent heels.
