Abbey, Harry and Tom - who are all former winners of the show - have been added to the line-up of the festive edition in December, BBC have confirmed.
They will be joined by other stars of the show including Alison Hammond and Lisa Snowdon, and for the first time ever, former royal marine medic Cassidy Little, who was the winner of The People's Strictly for Comic Relief 2015.
All six couples will each perform an enchanting and magical routine themed around a host of family favourites including Alice in Wonderland, Jack Frost and Scrooge, but who will lift the famous silver trophy?
The pairings are:
Abbey Clancy & Brendan Cole
Alison Hammond & Robin Windsor
Cassidy Little & Natalie Lowe
Harry Judd & Jo Clifton
Lisa Snowdon & Pasha Kovalev
Tom Chambers & Oti Mabuse
Darcey Bussell, Len Goodman, Bruno Tonioli and Craig Revel Horwood will also be on the panel judging, and the night will see a spectacular music performance from the legendary Dame Shirley Bassey. Sir Bruce Forsyth will return to host the annual Christmas Special with Tess Daly.
Strictly Come Dancing Christmas Special 2015 will air on BBC One on Christmas Day.
