Denise Van Outen dislocated a rib during rehearsals this week, while gymnast Louis Smith says he will need a knee operation after the contest ends. 'That'll be the Cuban heels,' he joked at a press conference on Friday.
Kimberley Walsh and Dani Harmer are also in the final, which is broadcast from 1830 GMT on BBC One on Saturday. Girls Aloud star Walsh also dislocated a rib in preparations for the semi-final. 'When you've got to do anything that stretches, it's like you've been winded,' she said. 'So laughing, coughing, sneezing anything, very painful.'
Smith, who is the bookmakers' favourite to lift the glitterball trophy, said his biggest worry was 'doing my back in and just collapsing on the floor on live TV. Not being able to move, with the music still going.' Harmer, however, said she was 'in perfect health' going into the final.
Despite the injuries, the celebrity contestants are in high spirits, with a slightly hysterical end-of-term atmosphere infecting the backstage area. The stars spent Friday morning watching each other rehearse, with a fumbled routine by Harmer and her professional dance partner Vincent Simone proving to be the source of much hilarity.
Pressed for details, Walsh explains: 'The way they're supposed to end the routine is the normal version, and they ended slightly x-rated.' 'It'll be alright on the night. If not, we'll style it out,' adds Harmer. 'It'll be ok, right?' laughs Simone. 'If I end up on top of her, it's a happy ending.'
Saturday's final will see all four couples perform a showdance and a repeat of one of their earlier routines, chosen by the judges. The show takes a break for an hour at between 1950 GMT. When it returns, one contestant will be eliminated, and the remaining three contestants will be allowed to perform their favourite dance from the show's 14-week run.
