THE GREATEST SNOWMAN: LINE-UP REVEALED FOR CHANNEL 4 SPECIAL

The ultimate yuletide snowman building competition returns to Channel 4 this Christmas, hosted by Sue Perkins.

Five celebrities take on three increasingly tough snow sculpting challenges, carving their perfect Christmas gift, building extravagant snow castles, and finally creating their towering statement in snow: The Greatest Snowman.

The celebrities taking on the snowy challenge this year are reality TV legend Gemma Collins, choirmaster Gareth Malone, presenter Melvin Odoom, comedy actor Joe Thomas, and documentary star and DJ Yinka Bokinni.

The celebs are judged by celebrated British sculptor Taslim Martin alongside Swedish snow artist sisters Sara and Emilie Steele, and last year's champion and the dark lord of the snow Laurence Llewelyn-Bowen returns to scrutinise the cool creations.

There's a chance for the celebs to indulge in plenty of festive frolics in a magical Christmas wonderland, but don't let the frivolity fool you - the competition is fierce, and only one snowman-building star can hold aloft the glorious Greatest Snowman trophy.

Who will show the most improvement across the three challenges and display the powdery prowess needed to be crowned champion?

The Greatest Snowman airs this Christmas on Channel 4.
