Lauren's first dance is a Wild Wild West themed hip-hop with Twitch, choreographed by Tabitha and Napoleon. There is some concern about whether she's too good-girly to pull it off, but in the performance, she is amazingly good. Plus, there is this flip and roll maneuver that makes me do something I haven't done in a long time on this show -- rewind immediately, in the middle of the performance, to see the move again. Whoa. Adam Shankman says, "Who are you?? ... You just tore it up out there." He loves that she was totally lost in the music and in the moment. Mia Michaels says she pulled off the hardness of the dancing and kept her sexy girl side at the same time. Kenny first says how he's such a fan and happy to be on the show. Also, he loved the performance. He says Lauren has enough energy to power Los Angeles. Nigel says Lauren has grown so much this season, and that she was "bad," "nasty," "buc" and "sick."
