There must be some more history between Chris and Will otherwise that’s a fairly strong (over) reaction there by Will. or maybe he just snapped after a lot of pressure, remember all that talk about them having an open relationship but Jada being the boss and her history with Tupac? Will got a bit emasculated there and trying to take back some power? Weird way to do it though, on that stage. imo he‘ll definitely have to pay some sort of price for that slap.
People were saying he got punched. He got bitch slapped - huge difference. Something that comedians make jokes about all the time. he didn’t press charges, he can use this for material the rest of his career.
