Britain's Got Talent aired a scary invisible Phantom act during the show tonight - and fans are convinced they know who is behind it.
The ITV show returned to our screens this evening for an exciting - but creepy - routine, which saw judge Amanda Holden take centre stage as she was hypnotised by the 'invisible' person, who wreaked havoc across the stage.
At the iconic London Palladium, the invisible person made Alesha Dixon choose an item out of the box, which Amanda guessed correctly, and also eerily wrote on a chalkboard, despite no one being there to do the writing.
