Channeling Sia's favorite dancer Maddie Ziegler, the Dancing With the Stars star patted his tummy, did some amazing hand motions and some even more impressive jumps. He even got a lift from his female backup dancers. And let's not overlook his very emotional facial expressions. He clearly is feeling this. Julianne certainly loved it "Even if I don't win, he's never going to live this down," she said. "That was the greatest thing I've ever seen."

Unfortunately, Hough's dance could not overtake the fact that his little sis pulled out all the stops for her performance of Lonely Island "I Just Had Sex," not to mention that she brought out Meghan Trainor for her performance of "All About That Bass." Watch it - here.
