The finalists compete in two rounds of dance, one in which a judge helps the couples choose the creative elements and a freestyle number; performances by Meghan Trainor and Ariana Grande.
The couples take on a style of dance that hasn't been performed yet, a trio and a dance-off challenge.
All 13 couples return to perform; musical performances by Alexander Jean, Andy Grammer, Chaka Khan, Elle King and Nick Carter; the winner is announced.
