Oscars king hit as Will Smith smacks host Chris Rock

The Oscars was sent into chaos on Sunday night as actor Will Smith broke character and smacked host Chris Rock during the live broadcast.

Smith strode onto the stage and slapped Rock hard across the face after a seemingly innocuous joke at the expense of Will Smith’s wife Jada Pinkett Smith.

With the camera showing Smith laughing along with Rock just seconds before, the audience laughed and clapped at what they first assumed was part of the joke.

But things went very quiet when Smith started shouting profanities at Rock when seated again.

Rock managed to regain his composure and carried on with the show, while Smith returned to the stage shortly after to collect the Oscar for Best Actor.

During an emotional and somewhat rambling acceptance speech Smith gave a quasi apology to the Academy for his bizarre outburst but failed to mention Rock.
