Dude, WHAT is happening?!

Justin Bieber was visibly emotional and distraught when we caught him driving around LA this morning, and clearly he's got some pretty serious issues he's struggling with.

In the last few weeks, he's been photographed openly weeping in various public places, from Central Park to most recently at Harry Potter World on Sunday in Orlando.

A fan got a video of JB crying as Hailey Baldwin tried to comfort him over their butter beers, and some eyewitnesses claim they heard the couple discussing his ex Selena Gomez. Could that really be what this is all about? And if so, is his supermodel wife that much of a saint that she's being so understanding about his conflicted feelings?

We've got a few other theories about what could possibly be going on...

Either The Biebs has totally had it with being famous and wants to quit the biz entirely, or perhaps his business managers are putting too much pressure on him to get back into the studio and release new music? There's also a chance that his team is forcing him to annul the marriage so that he can get a proper pre-nup and tie the knot with Hails after all his assets are secure?

Whatever is going on, he better figure it out before he torpedoes his whole personal and professional life!
