Britain's Got Talent has revealed the full line-up for its forthcoming Christmas special, including the return of 10 previous winners.
Earlier this month, it was confirmed that the ITV talent search would return for Britain’s Got Talent: Christmas Spectacular – a festive special which will see all four judges including Alesha Dixon, Amanda Holden, David Walliams and Ashley Banjo perform alongside previous finalists for the first time ever.
Airing on Christmas Day (December 25), the line-up for the special has now been announced.
Spoiler: it's pretty incredible.
