Grab your glitterballs and join Sir Bruce Forsyth and Tess Daly for a sparkling spectacular as all 15 couples hit the dance floor. Every step counts, as the judges' scores from Week 1 are combined with those from this show. The celebrities are now dancing for survival, as the two lowest-scoring couples must face the dreaded dance-off in Sunday's results show. The pressure is on, as no-one wants to be the first to leave the competition.
