On Sunday night, Machine Gun Kelly Instagram posted a dramatic photo of him playing in front of a sold-out arena in Orlando with a shirt mocking Eminem's "Killshot" diss of him.

The photo was a little deceptive: he was opening for Fallout Boy so that was really their crowd.

And it looks like Fallout Boy's crowd booed MGK when he did his Eminem diss "Rap Devil." At least according to this now viral video.

There are also multiple Twitter reports that MGK deceptively staged the photo with the anti-Eminem shirt. (Hit play on the video to see the Tweets.)

This is how @machinegunkelly faked his "killshot" picture and got booed for performing #RapDevil (actual footage). Please share this so channels like @TMZ will stop spreading nonsense. That wasn't his crowd and they weren't impressed. @Eminem #Killshot #KellyGetsAnElly pic.twitter.com/1zh5ZFt84H

Hmm. It could be that all of those boos were added into that video. But, as of now, that's a really, really bad look for MGK.

Update: The boos may be fake:
