Hayden Panettiere was also a winner, receiving the Futures award for her work for protecting ocean animals. Donning a sexy lace top paired with a snug, orange skirt, the newly-engaged actress encouraged her fans to focus on important issues and avoid certain Twitter-trending distractions.
"Twerking is not going to solve global warming," the Nashville star quipped as she accepted her award. "In fact I think it speeds it up."
She was joined by fellow green-thumb celebrities like Lance Bass, Wilmer Valderrama, Daryl Hannah and Malin Akerman.
