This year's festive edition of the BBC ballroom dance show, which will air on Christmas Day, will feature six new stars taking to the dancefloor and a team of Strictly All Stars from previous series, who will dance a group routine.
Ex-Bolton Wanderers star Muamba, who collapsed on the pitch during an FA Cup match earlier this year, comic Katy Brand, actress Sheila Hancock, TV presenter Helen Skelton, popstar JB Gill and Bobby Ball are the celebs taking to the dancefloor for the first time.
The All Stars lineup features Rachel Stevens, Kelly Brook, Chelsee Healey, Colin Jackson and former series winners Tom Chambers, Natasha Kaplinsky and Chris Hollins.
Show favourites Ann Widdecombe and Russell Grant will also make a guest appearance.
Bruce Forsyth, Tess Daly and judges Craig Revel Horwood, Darcey Bussell, Len Goodman and Bruno Tonioli will all be involved and helping decide who takes home the Christmas Champions title.
Rod Stewart is confirmed as the guest musical act and will be performing 'Let It Snow'.
