For those who think Will Smith slapping Chris Rock was fake, there may be evidence to prove your case. A video has surfaced of Will showing a young fan how to create a real slap. During a press junket for “King Richard” Will is seen coaching the youngster on how to turn his head as he pretends to slap him. The footage was shot back in November and the little guy, whose name is Chris ironically, is practicing his best head turn as the veteran actor follows through with his slapping motion.
