This may or may not be true but what if the camera recording him is flipped?
Example: He might be on the right side of tyga but it shows up him being on the left side. (Camera is inverted)

If he wants to have fake tats then let him be like that

Obviously fake, Probably did it on purpose to start up a media storm.

That is very questionable. Maybe he couldnt make up his mind on which side it looked better on.

It looks fake to me just look at pictures of Justin bieber and you will see that its fake in that video!

It does look fake and yeah they could photoshop it into every video. Not that it matters.

Notice how the watch also switches. It's simple, the camera was inverted at some points

Does it matter? Don't give him any recognition, no one likes him.

the boy is too weak to stand the pain of a tattoo.

I think it's well of being photoshopped unless he stupid enough to ask for that even tho Justin has a real tattoo on his left arm, not his right? (I believe)
