Overview: Tess Daly and Claudia Winkleman welcome you to what looks like being another exciting results show. Thirteen become twelve, as once the judges' scores have been combined with viewer votes the lowest scoring couple will sadly have to leave the competition. Plus our professional dancers treat you to a very special West Side Story dance mash-up, and the stars of the brand new 2011 film version of Footloose cut loose on the dance floor with an exclusive performance just for us.
