Kelly Osbourne and Louis Van Amstel have the rumba for their first dance. Kelly has to do a solo in part of the dance, and she doesn't look super comfortable in that part, but the rest is done well. Sharon is jumping up and down in the audience; it's so cute. Carrie Ann says she totally gets it, and that she was brought to tears by her performance. Len say she has turned into an "absolutely competent dancer," but he doesn't think this was her best. Bruno agrees that she's endearing, but that the rumba should have a relentless sense of eroticism and this didn't. Scores: 8-8-8, for a 24/30.

Mya and Dmitry Chaplin dance the waltz for their first performance of the night. Their dance is just breathtaking and, yes, in a different league than everything else we've seen tonight. Gorgeous. Len says he loved it and it had romance and total control. "It was an absolute joy to watch." "That was love set to music," says Bruno. Carrie Ann says she loved it too, but that she has the potential to get 10s every single week and she thinks they lacked a hair of connection in their hold. Everyone boos. Scores: 9-9-10, for a 28/30.

Donny and Kym return for the samba. Booty-shaking notwithstanding, this style is much more in Donny's comfort zone. He looks confident again! Mr. Heart on His Sleeve cheers for himself afterward. Bruno says he came back and nailed it. Carrie Ann says this was better but it felt a little sloppy. Len agrees with Bruno and says this was a metamorphosis. Scores: 8-9-9, for a 26/30, for a 47/60 total.

Joanna and Derek dance the cha-cha-cha. Augh, why the return of the fringed pants? The performance is OK, but it seems a little slow, a little restrained. Carrie Ann says they did a great job. Len says it was clean, quick and had great rhythm, but could have been more cheeky. Bruno calls her "natural sex" and says she has set a very high standard. Scores: 9-9-9, for a 27/30, and a 54/60 total.

Kelly and Louis dance the quickstep for round two. Holy speediness, Batman. They are ALL OVER THE PLACE to "99 Red Balloons," and the crowd is in love. Len says two people loved that: "your mum and me." Bruno says she was like Speedy Gonzales, though she missed one teesy step. Carrie Ann says she nailed it and that she stayed with Louis the whole time. Scores: 9-9-9, for a 27/30 and a total 51/60.

Mya and Dmitry are next with the salsa. In the intro segment, Mya calls her self "this Maryland girl," and I'm like, hey, wait a minute ... did I miss a local this whole season? But everything I have read about her places her in the D.C. area. Now I'm confused. They dance to a supercharged version of "La Isla Bonita," and it's FAN-FREAKING-TASTIC. So fast, so amazing, so good. Bruno: "SEN-SA-TION-AL!" Carrie Ann says it was hot beyond belief and that it was good -- and complicated. Len says he was mesmerized by her buttocks (I swear that's a direct quote). He says she should absolutely be in the finale. Scores: 30/30, for a 58/60.

Last is the "knockout round," in which the couples choose the style and the song, for total creative control.

Kym and Donny do the jitterbug. It's goofy fun, fast and silly, and thankfully shorter than the first two rounds. Carrie Ann says he has his mojo back. Len says two out of three isn't bad. Bruno says he's recharged. Scores: 9-9-9, for a 27/30, and a 74/90 total.

Joanna and Derek take on salsa. It's fun, too, but I feel kind of bad for them doing salsa after Mya's amazing performance. I'm a little worried that Joanna is going to shake herself right out of her outfit. Len says it was hot. Bruno says it was delicious and flirtatious. Carrie Ann says she generates heat and that it was excellent. Scores: 9-9-9, for a 27/30 and an 81/90.

Kelly and Louis cha cha to "Girls Just Wanna Have Fun." It's so cute, but it seems short compared to the others. Bruno says she had precise timing and finishing all her moves. Carrie Ann says she did a great job, especially with her hands. Len says she did three dances to a high level this evening. Scores: 9-9-9, for a 27/30 and 78/90.

Last we've got Mya and Dmitry also with the cha cha. More fast, more fun. Carrie Ann says it wasn't speaking to her. Len says he was disappointed because he wanted it to go on a bit longer. Bruno says it was like an action-packed trailer for a blockbuster. Scores: 9-10-10, for a 29/30 and a total 87/90.

OK, so who is cut tomorrow night? I feel like it should be Donny or Kelly but won't be because of their fan bases. I think Mya's probably safe with those amazing scores and that fab salsa will get people on the phone. So ... Joanna maybe?

What do you think?
