As well as performing on the Strictly dancefloor for the very first time, the contestants will learn which of the professional dancers they will be paired with.
However, as our pictures show, they're not the only ones who will be strutting their stuff during the launch show. Host Tess Daly will join the professionals as they dance their way into the BBC studios, and new judge Darcey Bussell will team up with Ian Waite for a sensational showdance.
Expect fabulous outfits, obligatory jokes from Brucie and a whole array of emotions when the dancers learn who they will be getting up close and personal with during the next fout months.
