Britain's Got Talent viewers and judges were baffled on Friday night as Irish schoolboy magician Cillian O'Connor disappeared during his performance in the live semi-final.
Cillian, who has Autism, took to the stage and the screens of millions of viewers for the final live semi-final and again used judge Simon Cowell as part of his act.
Cillian asked Simon to write a random word on a handkerchief with his initials on it so that it was totally unique. Simon wrote the word 'dog' and left the hanky on the judges table in front of him.
