Conor McGregor argues with Machine Gun Kelly at VMAs

Conor McGregor barely regained his full health, and the dude is already back to the bob – only this time … he’s doing it well outside the Octagon, and against Kelly machine gun.

The UFC star appears to have had a physical showdown on the MTV Video Music Awards red carpet leading up to Barclays Center on Sunday – just before showtime, no less – in a potential clash that was captured by multiple photographers on stage.

As you can see, there’s Conor in the pink suit speaking to MGK who isn’t far away … and before you know it – the following shot shows Conor appearing to throw himself at the rocker as people intervene to separate them. No sign of Megan Fox here, BTW.

CMG can be seen reaching out to Kelly – but it doesn’t look like he’s ever caught it or even put his finger on him for that matter. Conor was pushed back by the safety at hand… with the Notorious looking angry and animated in the middle of the fray.

It’s unclear what triggered all of this in the first place – but it doesn’t look like it escalated beyond a brief confrontation … because we contacted the cops in the area, and no one reported this (for now). It’s weird … MGK and Conor don’t really have a hostile history.
