Heidi Klum was in a laser-cut silver Giles Deacon dress for this evening's American Music Awards in LA. She hit the red carpet without her better half, Seal, and will later take the stage as one of the program's many presenters. Heidi tweeted a photo of herself backstage giving two thumbs up, writing, "What an exciting night!"
