One more celebrity contestant will be eliminated from the competition.
Dancing with the Stars is a series that pairs a celebrity with a professional dance partner as they train and then compete in front of a studio audience in a televised dance competition. The pairs will be judged by a panel of experts and also by viewers at home, with one couple being eliminated each week.
In each round of competition, each couple will demonstrate how well their training and rehearsing has paid off, by performing a choreographed routine.
At the end of each performance, judges will give each couple a score. At the end of the broadcast, viewers will be instructed on how to call in and cast their vote for their favorite couple. In the results show the next day, one couple will be eliminated.
