Will Smith stormed the stage and smacked Chris Rock in the face on stage at the Oscars on Sunday night, after the comedian made a joke at the actor's wife's expense.
The kick-off began when comedian Chris joked about Jada Pinkett Smith's buzzcut, quipping: "Jada, can't wait for GI Jane 2."
Will - who went on to win Best Actor later in the evening - walked up to the stage and slapped the presenter, before returning to his seat and yelling: "Keep my wife's name out of your f****** mouth."
