Although Lambert was coy when it came to revealing precisely when his new single, written with Grammy Award-winning producer Pharell Williams, will hit radio, he's looking to the thousands of faithful Glamberts around the world to help with its music video. Lambert's directorial orders: to "lip-synch, sing, dance and dress up" with "prizes to be announced."
