Stephen ignored the second part of the statement when he read it aloud, but Alesha gasped in horror.
Amanda was in hysterics, but Simon jumped up from his seat in a rage and ranted: “David, you’ve actually crossed the line!
“You really are a smutty little man, aren’t you? Get out!”
David seemed to be pushing ever closer to the line after Simon told viewers on Monday night that David was “un-sackable”.
Simon was not impressed at all by David’s suggestion and gave him a stern telling off, prompting David to make a swift exit.
As the show went to an advert break, viewers could see Simon storm over to David to have a stern word.
Tonight’s instalment of the spin-off show saw Simon and Stephen highlight the previous night’s conversation.
Simon explained that the first thing David did when he saw him today was apologise.
He said: “Do you know what he said to me today? He said, ‘I really, really apologise for what I said last night’.
“It was the first thing he said when I arrived today. I said, ‘I’ve got no idea what you said’. And now he’s showing off again.”
David then reiterated: “I apologised. I apologised because I made a crude joke and I apologise. Not really!”
Express.co.uk has contacted representatives for Britain’s Got Talent regarding last night’s comments.
