Hayden Panetierre

A celeb with a cause is a great thing. For Hayden Panetierre, her passion is saving sea animals. On Sunday the 18-year-old star showed up at a Washington, D.C. demonstration that called for a stop to whale hunting. She spoke to the crowd, saying, "Not only are these animals being cruelly slaughtered, the meat is contaminated by huge levels of mercury. And we're not taking a stand because Japan is one of our biggest allies in the war on terror, but Australia is an ally and they've told Japan what they think, and good on them!"

Last fall she participated in a rally to protest the killing of dolphins in Japan. And she's not done yet. Hayden is visiting the embassies of Iceland, Norway and Japan to discuss the cause. She also has a Web site, Panettiere's Closet, that is selling clothes and accessories from her show. All proceeds go to the Whaleman Foundation.
