Tonight, all 15 couples will take to the floor and the show lasts a staggering two hours and five minutes!
Last week's double outing was a warm up for this weekend because the celebrities know for one couple it will be their last dance. Anyone who had a less-than-impressive turn on the floor last time, will have the chance to rectify it now.
But once the judges have given their scores, and the lines have opened, it's time for us to have our say. Who will we be sending home in tomorrow night's results show?
