Overview:It's crunch time as we head into the Results Show that will determine which three couples will be dancing in the finals. Right out of the gate, Hines & Kym learn they are safe. No neck injury is going to keep this team from going after that coveted Mirrorball Trophy. The legendary Stevie Nicks gets the crowd going with a performance of her new song "Secret Love." She's followed by a rousing routine from rapper Pitbull, featuring Ne-Yo and Nayer. A short time later, an inspirational young lady with a life-threatening disease takes to the stage. Her name is Tayla Kelley and she wows the crowd enough to earn a standing ovation for her dance routine. In between all that fun, Chelsea and Mark learn they are headed for the finals. Stevie Nicks returns to perform the classic Fleetwood Mac tune "Landslide" for an appreciative crowd. The cheers she receives continue as we learn that Kirstie & Maks are moving on. That means Ralph & Karina are headed home. The former Karate Kid turned out to be a fine Dancing Man during his impressive run. His gracious, genuine personality will be missed. Now it's onto the finals!
