Even the show's host Queen Latifah told the Dish Rag exclusively that she was moved by his real, honest emotion. "I thought Chris Brown's performance was amazing, just amazing," she raves. "Not only was it a knockout performance, but his heartfelt emotion ... you can't plan that, you can't write that. It's just truth."

Or was it?
