Naked for the planet: Hayden Panettiere
There's plenty of obvious reasons we'd all like to see Hayden Panettiere without her clothes on. But there's more to the actress than meets the eye. When she's not saving the world as Claire Bennet on Heroes, she's saving the planet in real life.Hayden's most notable animal-friendly endeavor involved a violent confrontation with Japanese dolphin hunters. The star, along with a group of animal rights activists, tried to free a group of seized dolphins by paddling out to their net on surf boards -- only to have the hunters smack them with a boathook. Ouch! Now that's dedication.
Plus Hayden is a vegetarian and has campaigned against Norwegian whale hunting -- as if she wasn't doing enough.
And, you know. She's really hot.
