Stephen Mulhern has addressed a fan theory he is behind Britain's Got Talent's Witch costume.
The haunting act has been one of the most memorable performances in the latest season of the popular ITV competition. Simon Cowell, Alesha Dixon, David Walliams and Amanda Holden were spooked as the character took to the stage reciting a creepy chant .
The judges were terrified as the Witch handed them apples and transformed the fruit into maggots and cockroaches. The Witch progressed through to the next round and fans have been trying to guess who is behind the make-up since.
