Justin Bieber was taken to a hospital last night after feeling short of breath during his third show at London's O2 Arena. But all is well—well enough for him to shoot back at a photog after being called a "fucking moron" and told to go back to America. 

He's from Canada.

Anyway, Bieber made himself look like a king for rightfully standing up to the photog and threatening to "Beat the fuck out of him." His bouncers got in between and Bieber was rushed off in his car. 

The 19-year-old artist took to Twitter this morning after the incident, saying:
