tonight. It's a big night for robin. Making her debut on "Dancing with the stars" as a judge. First, she's taking us backstage. Welcome, my darling. ? Right here, is your trailer. Oh, my, this is my trailer. This is your trailer. I'm going to let you in. Perfect. Let me see, oh, it's perfect. That is your robe. Do I get to keep it? Every season we get a new robe. It's got your name on it. I had the set deck arts make you your own special judge's notebook. This is yours. This is mine. The dancers are not allowed in the production office. Nor are the judges allowed with the dancers. The trailers for the dancers are there. And the judges are way on other side. And never shall the two meet. The dolce vita look for you. Welcome, my darling. You are hot. So are you. What do y'all think, quite a reaction, pro and con, about switching partners. Whoo! I hit it, I hit it. I think that is the excitement of the season. I'm curious to see what the audience has done. A show with the people, and by the people. Choosing a costume is such an integral part of making yourself look good and feel good. It's an important part of the process. Our team is incredible. Ooh. It's nice! Beautiful. Look at that. Look at that. Oh, that is gorgeous. This is behind the scenes, people. I never get to do this. You should come every week. I give you a 10! 10! All three of you. Thank you, guys. Oh, my gosh! Val! Hey, robin. How are you? Great to see you. You look beautiful. You can't interact with the dancers very much. I know you danced together. I'm going to give you a kiss, but -- We can't -- A little more action. That's all we ever get. We all thought you saw each other throughout the week. No? Val, we love you. I'm take her away. Thank you. Good luck. Are you ready for this, robin? It's paddle time. This is your own paddle. Robin Roberts? 10. Are you ready? Yes, yes, I'm ready. You can watch robin tonight at 8:00 P.M. Eastern on "Dancing with the stars." And to see photos behind the scenes, go to our website, goodmorningamerica.com on Yahoo!. She was dancing already a little bit. She is ready. Get that wrist move down. Best of luck, robin.
