Will Smith's got people in his corner following his on-camera altercation with Chris Rock ... getting a big hug from Trevor Noah at the Vanity Fair after-party, having a long, and private, conversation.
Will was still emotional when he got to the party Sunday night in Bev Hills, taking pictures with tears in his eyes ... which is when Trevor came up to the Best Actor winner.
They embraced for quite a while -- more than 1 minute -- clearly trying to have a conversation over the loud music blaring in the room. When it was all said and done, they smiled at each other and posed for some photos.
There's no doubt what they were discussing for so long ... Will slapped Chris Rock after his "G.I. Jane 2" jab at Jada Pinkett Smith.
The crowd, and even Chris, was stunned ... things got more real after Will continued to shout "Keep my wife's name out your f****** mouth" from his seat.
Trevor tweeted after the slap heard, and seen, 'round the world ... saying, "Wtaf????? That wasn’t scripted?????"
Safe to say he had some questions, and maybe got them answered when he and Will hugged.
