Let's Dance is a German dance competition television series that premiered on April 3, 2006, on RTL and filmed live in Cologne. The show is based on the British BBC Television series Strictly Come Dancing and is part of BBC Worldwide's Dancing with the Stars franchise. The format of the show consists of a celebrity paired with a professional dancer. Each couple performs predetermined dances and competes against the others for judges' points and audience votes. The couple receiving the lowest combined total of judges' points and audience votes is eliminated each week until only the champion dance pair remains. Format Celebrities dance in the programs with a professional or successful tournament dancer in several dances. At the end of each performance, each jury member gives a score between one and ten. Which couples on the next Let's Dance show will participate and which not, will be determined by the jury rating and the audience, who can vote for their favorites by telephone at the end of the program. The last placed in the jury evaluation receives one point, the penultimate two points and so on. The same applies to the placements of the audience rating. (The organizer does not publish the results of the audience rating (number of callers or ranking list).) The highest placed person receives as many points as there are still couples in the race in the respective episode. Jury and spectator ratings are added together, the pair with the fewest points is eliminated. If there are several last-placed couples with the same rating, the couple with the lowest audience rating will be eliminated. Cast Hosts Nazan Eckes has been the host for seasons one to three. In season one and two, her co-host was Hape Kerkeling and in season three Daniel Hartwich. Between season four and ten Hartwich has been presenting alongside Sylvie Meis. The program is currently hosted by Hartwich and Austrian singer and former winner Victoria Swarovski. Daniel Hartwich was replaced by Oliver Geissen in the first regular show of season 11 and by Jan Köppen in fifth regular show and the final of season 15.
