The contestants will dance two dances – a judges' pick and then a showdance. After that the finalist with the lowest votes will be eliminated and the three remaining will perform their favourite routine of the series.
So, who's doing what? The judges' pick is being kept secret until the night, we do know the showdance music: Caroline and Pasha will perform to Beverly Knight's version of Angels, Frankie and Kevin are dancing to Get Happy by Judy Garland, Mark and Karen are getting down to Queen's Don't Stop Me Now, and Simon and Kristina will perform to A Little Less Conversation by Elvis.
It's been a brilliant series, but who will Tess Daly and Claudia Winkleman be giving that glitterball trophy to?
