Some people are saying that it was “fans” that he cursed out but if you watch the video above, it is clear that they are not fans. They are clearly mocking Justin Bieber and deliberately trying to agitate him.
In the video you can see the girls and they are laughing about how they just saw Justin Bieber on a ride. They joke that they have Bieber fever and wait for him to come around again so they can take a picture. When Justin comes back around, you can hear one of the girls say: “I have Bieber fever!” and then you hear Bieber say: “F**k You!” It also looks like he flips the girls off.
Now, he probably shouldn’t have used that language, but the girls were being extremely rude and annoying. Plus, they probably wouldn’t have even come close to snapping a photo of Justin with their crappy camera work. It was like watching, ‘Cloverfield’ all over again.
