Hosted by Tess Daly and Claudia Winkleman, the festive foursome on the judging panel are, Craig Revel Horwood, Motsi Mabuse, Anton Du Beke, and Head Judge, Shirley Ballas.

Taking to the dancefloor this year is Adrian Chiles with his professional partner Jowita Przystal; Anne-Marie and Graziano Di Prima; Fred Sirieix and Dianne Buswell; Jay Blades and Luba Mushtuk; Mel Giedroyc and Neil Jones; Moira Stuart and Aljaž Škorjanec.

The Christmas special will start with a sensational group routine featuring the celebrities and their professional partners, alongside some of their fellow Strictly professionals.

And, as well as dancing, there’s plenty of music, with two very special performances from Jamie Cullum and Gary Barlow.

Strictly Come Dancing Christmas special will air on BBC One and BBC iPlayer on Christmas Day at 5.10pm.

Q&A with Moira and Aljaž

How are you feeling about being a part of the Strictly Christmas special?

Moira: I am still amazed. I am so excited and grateful to have Aljaž beside me to teach me to dance, he is just magnificent.

Aljaž: I am beside myself that I get to dance with the legend that is Moira Stuart. I have seen you on the TV since I came to the UK, and now to get to dance with you is surreal!

What made you want to take part?

Moira: I have watched Strictly from the beginning, I have been asked before and I always thought I couldn’t do it, my approach to dancing is so visceral. Then I thought, let’s have some fun and challenge myself.

What did your friends and family say?

Moira: I have only told my two sisters, they are both abroad, and simultaneously they were silent! I think in shock!

Tell us about your partnership, what’s training been like?

Moira: To be brutally truthful, Aljaž has made it less arduous than I expected, he has made it fun, which is tremendous. My problem is, I can only react to him and the music, the counting doesn’t mean anything to me!

Aljaž: I am a bit like her Metronome! From day one, it has been great, I love that we are doing a salsa, it is so groovy. We have Cameron too, who is playing Santa in our routine, he is one of the best Santa Claus’ I have ever seen.

How do you feel about being ‘Strictly-fied’ festive style?

Moira: That has been the easiest part! It has been a giggle and delicious, I am wearing something I thought I would never ever wear, it is out of my comfort zone and I love it!

What would you buy each other for Christmas?

Moira: I think as a giggle I would give him a tiny elf hat to remember me by.

Aljaž: I would give her a beautiful pair of ballroom shoes, so in the new year she could go and boogie a little bit, I think she’d love it.

How do you rate your chances of being crowned Christmas champions? Who do you think your biggest competition is?

Moira: Oh everyone! From what I am seeing, I am jealous as hell! One thing I have missing in me is a competitive bone, to me it is a giggle, I just want to enjoy it!

Aljaž: I will say it for both of us, the only right thing this Christmas will be looking at that trophy!

How do you rate yourself as a dancer?

Moira: I was dancing out of my mother’s womb, I have been dancing forever. Now Aljaž has given me a new dimension, and I will hold onto that with everything.

What’s your favourite Christmas movie and why?

Moira: It’s A Wonderful Life. It’s gorgeous.

Aljaž: I am going slightly different, with Elf. It just puts a smile on my face, and that is who I am playing in the dance too.

What song gets you up dancing at festive parties?

Aljaž: Last Christmas by Wham, or anything that Mariah Carey or Michael Bublé sing!

Moira: I just love Nat King Cole.

Brussel sprouts - yay or nay?

Moira: Oh no. I was addicted to brussel sprouts, with a little bacon, delicious. I once gorged on them, and they repeated on me in the most extraordinary way, so now I haven’t had them for a while.

Aljaž: I’d never really fully tried them before coming to the UK, it has a very particular taste, it’s a bit aggressive for me.

Best and worst Christmas present you ever received?

Aljaž: We do Secret Santa on Strictly. One year Neil got me a football shirt signed by Lionel Messi, everyone else was getting Lynx Africa gift sets, and I was over the moon!

Moira: My first teddy bear, I will never forget that.

Which judge are you most keen to impress?

Moira: Any of them! Please someone! If Craig gives me any point at all, I will be very grateful. I am in love with Anton! And with the ladies… please give me pity!

What are the Christmas traditions in your household? How will you be spending Christmas Day this year?

Aljaž: I am hoping to go home to Slovenia to see my nieces, one of who I haven’t met yet as she is 10 months old. So I am hoping that is possible.

Moira: My Christmas will be quiet this year, but my sister is a fabulous cook and she makes this wonderful cauliflower soup, which I usually fill up on before the main turkey dinner.

Any new year’s resolutions? Will you be taking your new found dancing skills into the new year?

Moira: Definitely! Other than that, I want health and happiness for everyone.

Aljaž: That’s lovely. I don’t normally believe in them, but I think the world can always be kinder, so I am going to try to make someone’s day, every day.
