Celebrities React to Will Smith Smacking Chris Rock, Son Jaden Approves

Will Smith's slap heard-round-the-world seems to have Hollywood kinda split on whether it was right or wrong -- but there's one person who's firmly in the guy's corner ... his son.

The entire world seems to have reacted to Will's violent behavior, and celebrities are no exception -- with several high-profile stars weighing in online ... and some even defending WS and Jada Pinkett by extension, including Nicki Minaj.

The rapper had a lot of thoughts on the matter, writing ... "You just got to witness in real time what happens in a man’s soul when he looks over to the woman he loves & sees her holding back tears from a “little joke” at her expense. This is what any & every real man feels in that instant. while y’all seeing the joke he’s seeing her pain."

She adds, "Imagine what it must feel like to be losing your hair to the point where you have to shave it bald. You think that’s easy to deal with for anyone?"

So, clearly ... Nicki is team Will/Jada. But, there are far more who condemned the assault -- including Judd Apatow, who was emphatic. Judd wrote, "He could have killed him. That's pure out of control rage and violence. They've heard a million jokes about them in the last three decades. They are not freshmen in the world of Hollywood and comedy. He lost his mind."

Others seemed to be either baffled or amused by what had occurred ... Billy Eichner, Jodie and Conan O'Brien fall into that category. But, the most telling response came from Will and Jada's own flesh and blood.

Jaden Smith sounded off in the aftermath, writing ... "And That's How We Do It," apparently co-signing what his old man had just done.

It would also seem that Jada herself appreciated Will getting up there -- because as soon as the broadcast went to break ... a photo shows Chris Rock leaning down from the stage trying to talk to both of them, with none other than Denzel Washington standing in between them.

In the pic, you can see Will and Jada holding hands ... appearing to put on a united front.

There's also a lot of chatter today about "toxic masculinity" and whether Will is a personification of that. Many feel he is, but there seems to be an opposing group who say he was simply doing what a good partner/man should do to defend his woman.
