Simon Cowell stormed off the stage tonight, during a live act, after he was left fuming.
Simon and David were both forced to become involved in a ventriloquist's act and Simon grew increasingly uncomfortable.
The judges were forced to can-can dance, after being involved in very awkward dialogue.
And that's when Simon decided he'd had enough, as he removed the mask and stormed off the stage.
David asked Jimmy the ventriloquist what he was going to do next - and he was speechless, before saying "erm I was just going to put you in the box."
Simon then eventually walked back in stage, so the act could finish - but he was clearly unimpressed by his ordeal.
However fans absolutely loved it on social media.
One said: "I can’t believe Simon walked off! The jokes were so cringe though, I’d have been embarrassed too."
Another said: "The greatest moment in #BGT history just happened... Simon walked off in a massive strop."
And a third said: "Simon walking off stage Hahahahahahahahahahahaha dying! Pushed way too far."
*BGT continues at 7:30pm on ITV tomorrow
