The Top 14 Perform - S4.E12

Host Cat Deeley promised at the outset that the final 14 dancers will face some changes and the competition would get more difficult for the final seven couples. She soon explained that each of the couples would have to dance twice for the first time this season. Hip hop choreographers Napoleon and Tabitha Dumo served as guest judges, joining regulars Mary Murphy and Nigel Lythgoe.
