This week, Cat introduced us to Nigel Lithgoe, Mary Murphy and Dan Karaty as our judges. Then, the dance performances started. Donyelle and Travis performed a hip-hop routine, Allison and Ivan danced the Argentine Tango, Natalie and Ryan danced a disco routine, and Heidi and Benji danced broadway. For the second round, Donyelle and Travis performed a quick step, Allison and Ivan danced hip-hop, Natalie and Ryan danced a contemporary routine, and Heidi and Benji closed the show and performed a mambo. Afterwards, voting was opened up to the audience. (thetvdb.com)
