Laurence Llewelyn-Bowen to appear on The Greatest Snowman

'Changing Rooms' host Laurence Llewelyn-Bowen has signed up for Channel 4’s festive show ‘The Greatest Snowman’.

The 56-year-old interior designer will be swapping a paint brush for an ice pick instead on the programme which will see celebrities tasked with building the best snow and ice creations with the held of a team of experts and engineers.

The show will culminate with the stars having to build the greatest snowman, and producers are expecting plenty of seasonal innuendo for good measure.

A source told The Sun newspaper's TV Biz column: “Laurence is planning a Russian Cossack-style snowman. Of course, it’s elaborate.

“These personal flourishes are what will make the show so funny.”

Sue Perkins is set to host the one-off festive special.

The source added: “With Sue in charge, we are expecting lots of cheeky puns about snowballs and snow globes.”

Other celebrities rumoured to take part in the snow-building competition include Cherry Healey and Liam Charles from 'Bake Off: The Professionals’.

Channel 4 previously said of the programme: “With thousands of tonnes of snow and giant blocks of crystal-clear ice at their disposal, the celebrities will go head to head across three tough rounds that will test both their brain and brawn.

“Supported by a crew of seasoned sculptors, engineers, and snow builders, these stars will have to design and create some of the most extraordinary snow creations ever seen on TV.

"Judged by experts, all will risk chilblains as they attempt to carve and construct incredible structures made from snow and ice,

"The competition will culminate in the ultimate snowy challenge where the famous faces will use all they have learned in each round to attempt to construct the greatest snowman."

The show is set to be Sue's first project for Channel 4 since 2003 as the host of 'RI:SE', while she appeared on 'Celebrity Big Brother' the previous year after a stint alongside Mel Giedroyc hosting 'Light Lunch' and 'Late Lunch' in the 1990s.

Neither Mel nor Sue made the jump to Channel 4 when 'The Great British Bake Off' moved from the BBC in 2016.
