The Top 12 Perform

Host Cat Deeley reminds viewers that the final six couples will be competing for a place in "your" Top10. We're introduced to the final 12 dancers, followed by judges Mia Michaels, Mary Murphy and Nigel Lythegoe. Chelsie & Mark: Up first for the couple is an Alex Da Silva-choreographed salsa (mmm, salsa), featuring tricks Chelsie thinks are "insane." Nigel says it was a "great routine to open the show," praised the footwork of both dancers and makes a thinly veiled and disturbing erection reference. The routine "worked" for Mary, who singled out Chelsie as "phenomenal." Mia thought the routing was "smoking-hot," but thought Mark was awkward. Routine No. 2 was a Broadway number by Tyce Diorio which Nigel thought was hotter than Las Vegas. Mary raved that it was bluesy and sultry, though Mia was lukewarm on both dancers. Comfort & Thayne: Starting with a hip-hop number choreographed by Napoleon and Tabitha Dumo, Thayne fears he will look a "major white boy." Nigel thought the couple performed the moves capably but didn't think the two add of their personality and predicted we will again see them in the bottom three. Mary didn't think there was any chemistry and Mia was worried neither is doing enough to stay in the competition. The couple went contemporary for its second routine, with Nigel thinking Mandy Moore's choreography was better than the dancers. Mary didn't find it believable, and Mia liked Thayne far more than Comfort. Jessica & Will: The couples first routine was put together by Tyce Diorio, a contemporary number the choreographer believed "says the Garden of Eden" and both dancers seemed to like. Nigel thought the pair had a connection the previous two lacked, Mary called it "one of the most amazing pieces Ive ever seen on the show" and Mia added it was "perfect moving body art". Tony Meredith and Melanie LaPatin choreographed the couple's second dance, a quickstep ballroom number which seemed to terrify both dancers in rehearsal. Nigel was a fan of the routine but didn't care for the quickstep aspects of the performance. Ballroom expert Mary said it was "very heavy" and was glad the pair had a good first number to fall back on. Mia thought Jessica regressed and believed Will looked tired of having to carry the couple. Courtney & Gev: The couple's first dance was a cha-cha-cha to Rihanna's annoyingly catchy "Don't Stop the Music." Nigel thought it was "brilliant" and "great fun to watch," Mary screeched that "it was magic" and Mia called it "
