Emma Bunton looks ethereal in a floor-length white gown as she performs during the Strictly Come Dancing Christmas special, to air later this month. 

The former Spice Girl, 48, appeared angelic as the Blackpool ballroom was transformed into a picturesque winter wonderland. 

Standing in the centre of the dancefloor, Emma truly looked stunning as she belted out a tune for the BBC audience as they prepared to watch this year's star-studded line up compete to become the festive champion. 

She was stood on an elevated platform as she held on to the mic stand and flashed her left leg through a high leg slit. 

Adding inches to her petite frame, Emma slipped into a pair of towering sparkly nude heels. 

To accessorise, she kept it simple with a silver diamond necklace and a pair of matching earrings. 

As she performed for the festive special, dancers dressed in simple grey dresses can be seen twirling around her. 

Meanwhile in another hit, a line of string musicians can be seen joining the star on the dancefloor as they keep the audience entertained. 

Six couples will perform a festive fuelled routine in the hope of impressing the judges, Craig Revel Horwood, Motsi Mabuse, Anton Du Beke and Head Judge Shirley Ballas, and the voting studio audience. 

But who will emerge the Christmas star of the evening, and lift the sought after Christmas trophy? 

This year will see Racing Driver add TV presenter, Billy Monger, pair up with professional Nadiya Bychkova in the hopes to get his hands on the glitterball. 

Speaking about his national dancing performance on Christmas day, Billy revealed: 'I’m still figuring that one out of my head, but I'm excited. It's a bit of fun. 

'There’s a lot of learning but I'm trying not to think about the fact that it will be out on national TV on Christmas Day, and all my family will definitely be watching. 

'I’ll be watching through my fingers.'

EastEnders actress, Tamzin Outhwaite wiil also Billy in the glitzy line up as they will compete against Gladiator star Harry Aikines-Aryeetey, drag queen Tayce, comedian Josh Widdicombe and Vogue Williams on the show.

Tamzin spoke of her appearance: 'I've always wanted to do Strictly because I want to learn to Ballroom and Latin dance but I know that at my age, I don't think my body would be able to do the amount of weeks that is required. 

'So I said yes to the Christmas Special because it feel like a little snippet, a Strictly hors d'oeuvre. Like I could just dip in for a couple of weeks.'   

Meanwhile Vogue confessed: 'I said yes because it's just so fun. It's such a fun, brilliant show. I think if you’re asked to do something where you’re able to learn a skill, it's really cool. You get a professional dancer teaching you how to dance and you're getting to go out in an amazing costume. 

'Every single part of it, it's just so exciting to me. I love the idea of learning how to dance, especially because I'm not really a good dancer at all. I like challenging myself and this is a very big challenge. I think the problem is people think I look like I can dance. I don't know why they get that idea but I actually can't. It's a really fun thing to be able to try and learn.'

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