Hayden Panettiere beso whales blonde dress legs

Last night Hayden Panettiere hosted The Whaleman Foundation benefit at Beso, and as always, the Heroes hottie looked fab on the red carpet.

We know this organization is very close to her heart, and we love it when celebs raise awareness for causes they believe in. After all, who could forget the footage of Hayden breaking down in Japan two years ago when she witnessed the slaughter of dozens of the creatures? We cried too!
