'Dancing' Talks Sex!

Sexual tension is brewing in the ballroom! While Kristi Yamaguchi iced the competition with the first perfect score of the season -- which Carrie Ann called her "favorite dance performed this season so far," -- the other couples sizzled on and off the floor.

Shannon and Derek may have stiffened up on the floor, but they seem to have worked on their chemistry off camera! The pair gave "Extra" a song-and-dance routine by staying mum on their rumored showmance, after the two were caught kissing at the beach. It was Mario and Karina's wildly sensual Rhumba that was too hot for Judge Len Goodman, who decried, "It was too much for me!" Carrie Ann had a different take, saying, "That was better than good sex!"

Cheryl and Cristián also stepped it up last night, with a near-perfect Foxtrot that had Len making a bold promise... "If you're in the bottom two tomorrow, I'll show my bum in the supermarket!"

The evening was capped with the entire cast in a rollicking barn dance that was expertly choreographed and executed, with wild flips and acrobatics. Stay tuned to ABC tonight to see who will be performing their last dance. Ashlee Simpson and dancers from Riverdance will appear.
