Simon Cowell has ordered a string of last-minute changes to tonight's episode of 'Britain's Got Talent'.
The musical mogul - who produces the show as well as sitting on the judging panel with Amanda Holden, Alesha Dixon and David Walliams - was said to be upset that last week's debut episode was beaten in the ratings by rival 'The Voice' and is taking no chances on it happening again.
Even show staff are now said to be unsure which acts' auditions will air tonight because so many changes have been made, with spin-off show 'Britain's Got More Talent' also affected.
The ITV2 show's host Stephen Mulhern said: "Simon changes it up until the last minute, I've literally only just done the voice-over for the show that is going out tomorrow.
"He'll take stories out and he'll twist bits about and he'll say I don't want that there, and I want it there.
"He'll watch both shows throughout the week and chop them about, so I've had to come back in to re-do the voice-over.
"People don't realise how all over it he is.
"He is a judge but he also covers every bit of that show, there is not one bit that goes out that he hasn't signed off. I find if phenomenal, if not incredible.
"I had to come in twice! I was in Manchester last night so I had to travel back on the 7am train to be in for 9am, so they could deliver it to ITV for 1pm."
According to Stephen, Simon is more focused than ever on making this year's show the best yet.
He told The Sun newspaper: "We've had more conversations this year than we have in the past five years.
"The main thing he wanted to stress was that he was, and these were his words, 'Going to turn the show on its head'. "
