At Sunday night’s Oscar ceremony, Will Smith shocked the room by moving toward the stage and smacking presenter Chris Rock in the face after the entertainer poked a fun at Smith’s significant other, actor Jada Pinkett Smith.

Rock was on the Oscar stage to introduce the honor for best narrative. He started by poking a couple of fun at individuals from the show’s crowd, including Pinkett Smith-alluding to her as “G.I. Jane” because of her firmly edited hair. (Pinkett Smith has spoken in the past about her battle with alopecia.) Shortly after Rock made the joke, Smith strolled to the stage and smacked the humorist across the face. He then, at that point, got back to his seat and yelled, “Keep my wife’s name out of your fucking mouth.”
