Grab your glitterballs and join Tess Daly and Claudia Winkleman for a sparkling spectacular as all 15 couples hit the dance floor, together for the first time in a dance floor spectacular.
Every step counts, as the judges' scores from last week are combined with those from tonight's show. The celebrities are dancing for survival, as the two lowest-scoring couples will face the dreaded dance-off in Sunday's results show.
The pressure is on. No-one wants to be the first to leave the competition.
