Mel B throws water at Simon Cowell after he made a comment about her marriage to contestant.

It was a tense night at the judge’s table during “America’s Got Talent” (AGT) live show.

Simon Cowell pushed the wrong button and totally pissed off Mel B by jokingly comparing an act to her marriage:

“I kind of imagine this would be like Mel B’s wedding night … A lot of anticipation. Not much promise or delivery.”

In return, Mel B shocked the audience by throwing water at Simon and storming out.

“The act before made me cry, because it’s all about dad’s and cancer and I just lost my dad, he goes and says something stupid like that so then I got angry, “ she said after the drama.

Smiling, “How do you know what my wedding night was like all those years ago?”

Meanwhile, Mel eventually returned to finish the show but appeared to have ripped her dress in the process.
