Anything can happen on live TV is the message America's Got Talent is going with after last night's show which saw Simon Cowell making a joke about Mel B's wedding night, leading the former Spice Girl to throw water over her boss and storm off stage.

It all went down after there was a technical error with the performance of one of the contestants, Simon was then asked what he thought when presenter Tyra Banks went to the judging panel (yes, Tyra Banks hosts AGT now) and he said, "I kind of imagine this would be like Mel B‘s wedding night...."

At which point Mel B got up and threw her drink over Cowell with cheers from fellow judge Heidi Klum. Simon continued however and said, "A lot of anticipation, not much promise or delivery." At that point, as Tyra said, Mel B was OUT.

We don't blame her, while it was all obviously for theatrics, it was still a low-blow from Simon given that Mel B is currently going through a very messy divorce with husband Stephen Belafonte, who is also the father of her five-year-old daughter Madison. Mel B has also requested for a restraining order from Stephen and has previously made allegations of abuse against him.

So yeah, not your finest hour Cowell.
