If he's Justin Bieber...I'm definitely Chibs from Sons of Anarchy...I mean why would I have an ícone of someone who wasn't me...disregarding the fact that Mr. Chibs is fictional. Of course it's not Justin Bieber.
No, I'm pretty sure he doesn't know what the heck this spot is. And what's weird and scary is that I looked on this fórum on the Justin Bieber spot (not a fan, I was just curious) and this user was saying that he/she was Justin Bieber and the user said that he wasn't dating anyone and would be fine with dating a fan. A couple I remember called the user a poser, but there were two that thought it was really him. (Facepalm)
