The daughter of fashion royalty, Isabella Rossellini and Jonathan Wiedemann, Elettra has the modeling business in her blood. But her interests go far beyond catwalks and casting calls. Dedicated to helping educate the world — and herself — about climate change, Wiedemann helped found the organization Just One Frickin Day. She also helped to plan the FutureFashion show in 2008. Perhaps Elettra's eco-drive also comes from her mother, whose quirky video series on insect and sea creature sex for the Sundance Channel — smartly called Green Porno — has garnered a cult following.
