Strictly Come Dancing returned for its seventh series on 18 September 2009 on BBC One. Bruce Forsyth and Tess Daly returned as presenters of the main show on BBC One, while Claudia Winkleman presented the spin-off show Strictly Come Dancing: It Takes Two on BBC Two. Len Goodman, Craig Revel Horwood, and Bruno Tonioli returned as judges. Series 5 winner Alesha Dixon joined the judging panel as a replacement for Arlene Phillips. Darcey Bussell served as a guest judge beginning with the quarterfinal.
Camilla Dallerup, Karen Hardy, and Hayley Holt were replaced as professional female dancers by Natalie Lowe, Aliona Vilani, and Katya Virshilas. The show on 7 November was filmed from the Blackpool Tower Ballroom for the first time since the finale of series 2.
Due to illness, Bruce Forsyth did not appear in the show on 14 November. As a result, Tess Daly took over as main presenter, and Claudia Winkleman took over Daly's normal role.
BBC Breakfast sports presenter Chris Hollins and Ola Jordan were announced as the winners on 19 December, while Hollyoaks actor Ricky Whittle and Natalie Lowe finished in second place.
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 two couples with the fewest points are placed in the bottom two. If two couples have equal points, the points from the public vote are given precedence. As with the previous series, the bottom two couples have to perform a dance-off on the results show. Based on that performance alone, each judge then votes on which couple should stay and which couple should leave, with Len Goodman, as head judge, having the last and deciding vote.
Couples
This series featured sixteen celebrity contestants.
