Not only that, but the judges will also be taking part in a routine, with judge Craig Revel-Horwood announcing on This Morning, "They are taking a leaf out of Australia's book, the judges will be dancing. I don't know that Shirley Ballas knows that yet but she will be. We dance with the contestants, you put yourself on the line, so to speak."
But now it's been announced that there'll also be a brand new professional dancer thrown into the mix in the form of Nancy Xu.
Fans were stunned by the shock announcement of a new dancer, with many taking to the comments to congratulate Nancy - and wish her a happy birthday! One wrote, 'Oh I'm delighted! Saw you in "Burn the floor" this year and you are fantastic! Looking forward to watching you on Strictly.'
Another added, 'Wasn't expecting that ! Welcome, Nancy - loved watching you dance in BTF, you'll be a great addition to the show! And a very Happy Birthday!'
