This Christmas special really is the battle of the champions, as past series winners Abbey Clancy, Harry Judd, and Tom Chambers go head to head for the trophy with finalist Lisa Snowden, the People's Strictly winner Cassidy Little and 2013's bubbliest star, Alison Hammond. There's Christmas magic as our stars take on enchanting classics such as Alice in Wonderland, Puss in Boots, Scrooge, Jack Frost, Rapunzel and Hansel and Gretel. The judges embrace the Christmas spirit as they get into costume as characters from Snow White. Providing the musical performance are the incredible Shirley Bassey and Blake, with their beautiful rendition of Chestnuts Roasting on an Open Fire. It promises to be a festive treat for all!
