Simon could be seen looking “scared” once the routine had finished as he knew he had botched the dance.
As Stef and her guests watched the clip she said: “Look at your face at the end. You’re like scared.
“You look like a naughty boy.”
Simon, who was seen cringing as the camera panned onto him, said: “It still hurts me to this day because that was meant to be the best dance.
“We’d done it so well and I messed it up at the end.”
