Simon says, "I’m very angry it was used in the way it was on Saturday night. It was totally wrong and we can’t allow it to happen again. I’m mortified by what happened. The most important thing now is to ensure viewers can trust what they see on the show."

Do you believe he's "angry" or do you think it was his idea to use Auto-Tune in the first place?

Either way sources say that Saturday's show is being re-edited so let's all tune in and see if we can spot the difference in the quality of the singing.
