Kelly Clarkson is here to perform a mix of her new single and "Stronger." Love her. Saw her in concert earlier this year and she's amazing. And I'll be recapping her new show, "Duets," which starts on Thursday! Tristan and Anna and Tony and Kym come out and dance while she sings. When Kelly starts singing "Stronger," I get goosebumps. I'm an old married lady, but if I was a single chick who just got screwed over by some loser, this would be my theme song. Everyone is fist pumping and the troupe members are out on the dance floor. They cut up to the backstage area and all of the eliminated contestants are fist pumping too. It's just a great song.

Clip package looking back at the last few weeks of the competition, which leads into Derek and Maria's tango. I'm curious if it will seem smoother now that they've each had some time to heal from their injuries. I kind of would have liked to see their jive again, but this is fine. It's actually about the same as last time for me. Maria sometimes lacks grace and they don't have the intensity they had during the season when it was all on the line. They got eliminated at the right time.

Next season is All-Stars. I am reserving judgment until they announce the cast, because it could be really awesome or it could be really terrible. I would love to see, for example, Gilles go up against Jennifer Grey or Kristi Yamaguchi. But I don't want to see Kate Gosselin or Bristol Palin or anyone terrible like that.

Finally, some actual dancing by someone who's still in the competition. William and Cheryl are up first. In the roll-in package, William and Cheryl head into rehearsals right after last night's show to work on their final routine. There's a lot of "last day of summer camp" hugs involved.

And they are doing the salsa and William is repurposing his white pants, because he's no dummy. Even if he doesn't win this, people are watching, including casting directors. Anyway, William seems more joyful during this routine than I've ever seen him, and it's technically pretty good. He does stick his butt out a little too much, but he's right on the beat the whole time. Does it even matter what the judges say? Len has always been a fan of William, Bruno thinks no one does salsa better than William, and Carrie Ann thinks William has true star quality. Scores: Carrie Ann 10, Len 10, and Bruno 10. Are they really surprised? Unless someone really screws up, they're all going to get perfect scores at this point.
