Before the group "mega-mix" dance, the women had a product applied to their skin, and Kelly says the product caused a little commotion in her freestyle routine.
"And I was, like, trying to hold on with everything I had and I just couldn't do it," said Kelly. "They put 'body gleam' on us to make us look tan and sparkly, but it's like a lotion and I just slipped right away from Louis. I was so -- I was literally like holding onto his hand like that, like 'don't go!'"
Kelly and Louis ended the evening in third place with 76 out of 90 points.
Donny Osmond and his partner, Kym Johnson, came in second with 85 points. They got triple 9s for their Cha-cha, then ended the evening with triple 10s for a show-stopping freestyle.
"What a way to end this thing," said Donny. "I mean, it's the perfect ending. You know, this has been a ride -- up and down and in between everywhere and we ended on a high."
"We really did," said Kym. "It was just amazing."
Also amazing: Mya. She and her partner, Dmitry Chaplin, got a perfect score for their passionate Paso Doble.
Overall, they're two points ahead of Donny and Kym.
After the show Mya finally 'fessed up.
"I didn't want to say anything, but I've been dancing on a sprained ankle for five weeks and I didn't want to think about it," said Mya. "I just said, 'Whatever. OK, it's not an injury. It's just a sprain, whatever.' And I didn't want people to think, 'Oh, my performance has been compromised because of an injury,' but it's just how it is."
We'll find out who wins this season's "Dancing With the Stars" Tuesday night on ABC.
