The show was broadcast from Wembley Arena on 19 November with all proceeds going to the BBC charity, Children in Need. The finale took place in the Tower Ballroom at the Blackpool Tower and was the first episode to air in 3D. It was shown on BBC HD and in cinemas around the country.

Sir Bruce Forsyth and Tess Daly continued to present the main show on BBC One, while the results show was presented by Daly and Claudia Winkleman.

McFly drummer Harry Judd and Aliona Vilani were announced as the winners on 17 December, while Waterloo Road actress Chelsee Healey and Pasha Kovalev finished in second place, and actor Jason Donovan and Kristina Rihanoff finished in third.

Format

The couples dance each week in a live show. The judges score each performance out of ten. The couples are then ranked according to the judges' scores and given points according to their rank, with the lowest scored couple receiving one point, and the highest scored couple receiving the most points (the maximum number of points available depends on the number of couples remaining in the competition). The public are also invited to vote for their favourite couples, and the couples are ranked again according to the number of votes they receive, again receiving points; the couple with the fewest votes receiving one point, and the couple with the most votes receiving the most points.

The points for judges' score and public vote are then added together, and the couple with the fewest points is eliminated from the competition. The dance-off feature, where the judges choose which couple to save based on a final dance, was not utilised in this series. If two couples have equal points, the points from the public vote are given precedence.

Couples This series featured fourteen celebrity contestants. The full lineup of celebrities was revealed on 6 September 2011 on The One Show. As in the previous series, the celebrities did not know who would be their professional partner until they were introduced to each other at the launch show.
