WATCH: Mel B Dumps Water On Simon Cowell And Storms Off AGT Stage

Right after an America's Got Talent performance goes wrong with technical difficulties, Simon reviews the act with a joke that cuts at fellow judge, Mel B's on going divorce by saying;

"I imagine this would be like Mel B's wedding night... Alot of anticipation, not much promise or delivery."

Mel B promptly gets up, throws her water at Simon and storms off stage as host, Tyra Banks tries to take hold of the situation.

Watch it unfold here.

The official AGT twitter account also quickly addressed the situation as well by reinforcing what Tyra said; 

"[the show is] Live...crazy stuff happening."
