Definitely think it was real. They may be actors, but you can tell when reactions are real. JMHO. I thought Chris handled it all like a champ though.
This incident popped up on my YouTube so I watched it. Afterward, the opening monologue for the 2016 award show hosted by Chris Rock popped up. I thought it was for last night's show so watched it. Chris had some pointed jokes at Jada back then. Probably some built up resentment.
I could care less about who wins awards and whatnot, but do like the jokes at the expense of the rich and famous. I'll skip the original airing, but watch highlight YouTubes with all of the jokes/insults. It will be interesting to see how the jokes are handled next season. My hope is that whoever hosts uses the events from last night full bore, rather than being vanilla/super safe.
