Amanda Holden, Alesha Dixon, Ashley Banjo - who replaced Simon Cowell on the panel earlier this year - and David Walliams are all set to take to the 'BGT' stage for the upcoming show.

A source told The Sun on Sunday newspaper: "It’s been a chaotic year and show bosses wanted to treat audiences to something extra-special.

"It has never been done before and with Simon still recovering from his back injuries, it’s the perfect opportunity to get the judges singing, dancing and telling jokes for their suppers.

"Luckily, there won’t be anyone behind the panel to feed back on their performances."

Ashley will perform with Diversity, while Alesha and Amanda are set to sing during the Christmas special.

However, at the moment, David is remaining tight-lipped about what he'll be doing on the show.

The Christmas special was previously forced to postpone filming due to the coronavirus lockdown.

But ITV bosses are now pressing ahead with the show as it falls under the work exemption for Covid restrictions.

The source explained: "It’s going to be one big celebration without any voting or crowning of the winner, so everyone should be able to enjoy it.

"We will see the judges as we’ve never seen them before and it should give them a new-found appreciation of what the contestants go through."

Ashley's performance with Diversity will mark their first TV appearance since more than 25,000 people people complained to Ofcom about the group's Black Lives Matter-inspired routine earlier this year.

The 32-year-old dancer recently admitted to being shocked by the debate surrounding the performance.

He said: "I can’t think of another performance that has caused that sort of uproar and conversation. We had no idea what was going to happen once we performed it."
