Heidi Klum took the podium at last night's TeenNick HALO Awards at the Hollywood Palladium, and the supermodel paired a black and green Versace dress with several bracelets from her Wildlife collection. Who knew simple could be so sexy?

Heidi tweeted a shot of her and host Nick Cannon, who developed the awards show to help others and honor teens who are making a difference in their communities. We love it when celebs use their fame for a good cause!
