Was Justin Bieber Crying Last Night At The AMAs??? [VIDEO]

Some are saying that Justin Bieber got a bit emotional last night at the AMAs while The Weekend was performing.

I saw this happen LIVE last night on television and thought he looked a little sad, but this seems to proved it. That or maybe the flames on stage got to him.

Regardless, what or who do you think was on the mind of Bieber? He did end the show last night while a great performance and he did not seem to be crying towards the end---then again was performing under a waterfall, so.
