BRITAIN'S Got Talent's witch terrified countless viewers on Saturday night - but also sparked a major debate about who it is.
Several believe the character is a big return to the show for Marc Spelmann, who was behind the 'X' character in 2019.
However, others think there could be even bigger names behind the creepy character, who terrified Amanda Holden.
Some claimed the character could be Amanda's old friend Keith Lemon in one of his disguises.
The Celebrity Juice star, 49, is no stranger to dressing up and prosthetics from his days in Bo Selecta and playing her 'nan' Myrtle.
Other fans said it could also be one of Ant and Dec - both of whom also regularly don disguises on Saturday Night Takeaway.

One tweeted: "The Witch was either @lemontwittor or @antanddec."
Another wrote: "The Witch looks a bit like one of Ant & Dec’s Undercover disguises."
However, some couldn't decide which of the pair was in the costume, writing: "The witch is deffo Ant @antanddec in disguise!"
Meanwhile, another insisted: "Anyone else think the witch from last nights #BGT looked like Dec in prosthetics?"

When told both Ant and Dec were backstage one viewer insisted: "Maybe the video was edited to be like that or super imposed??"
The act began with the witch appearing on stage, stomping down the steps and handing out apples to each of the judges in turn.
When it came to Amanda the witch held her wrist and one hand and a gnarled stick in the other.
They cackled: "Do you know why they say beauty's only skin deep? Because we're all rotten to the core."
A third hand then shot out of the witch's black cloak and grabbed the apple in Amanda's palm.
It then exploded into a collection of cockroaches and mealworms, which wriggled and crawled around the judges' desk.
