Britain's Got Talent stars Alesha Dixon and David Walliams will attempt to prove once and for all which of them is the better judge - in a fiery clash on Lip Sync Battle UK.

Channel 5 confirmed that the duo will be fighting it out in the UK adaptation of the hit American show, which sees stars showing off their best miming skills in an attempt to triumph.

The show - hosted by Professor Green and Mel B - will kick off in the UK on Channel 5 in January and filming is taking place now.

And Digital Spy has heard that a raft of comedians have also signed up to take part, with Vic Reeves, Kayvan Novak, Katherine Ryan and Johnny Vegas all practising their best moves for their upcoming clashes.

A Channel 5 spokesperson told DS: "More names will be officially confirmed in due course."

Lip Sync Battle UK will kick off on Channel 5 on January 8 as part of the broadcaster's New Year schedule - which also sees Celebrity Big Brother starting on January 5.
