But you haven't witnessed the actual punch thrown by Bloom... UNTIL NOW!
The original video that surfaced online Tuesday night of the confrontation between this actor and this artist was grainy and taken from a weird angle. It was also brief and didn't zero in on the actual attempted knockout.
New footage has been been unveiled, however, and it makes it very clear: the stars exchange words, Bloom unleashes a roundhouse and one of Bieber's bodyguards gets in the way of its intended target:
Patrick Carney said Bieber should be happy with all the money he's made and not care about Grammys. Justin responded by telling his fans to "slap" Carney, which led to Carney calling Bieber "irresponsible."
