In fact, it’s involved with someone not even on the combat sport scene, it’s with singer/rapper Machine Gun Kelly.
Taking place at this year’s MTV Video Music Awards, it has been reported by TMZ Sports that McGregor got into a confrontation, where both he and Machine Gun Kelly had to be separated. Not only this, though, but an actual punch was thrown by the Irishman, as well as his drink!
The reports from TMZ come after footage went viral on Twitter of the scuffle, which can be seen down below.
The commotion apparently started after McGregor approached MGK to introduce himself, it was then that the UFC man was either given the cold shoulder or pushed by the singer or his security, which rubbed the former two-weight champion the wrong way.
The altercation may have also resulted in the Notorious’ walking cane getting knocked over and his drink spilling.
Speaking to Entertainment Tonight, Dublin-born McGregor said “nothing” happened.
He said: “Absolutely nothing. I don’t know. He showed up, and I don’t know. I don’t know the guy.
“Nothing happened with me, I only fight real fighters, people that actually fight, you know what I mean.
“I certainly don’t fight little vanilla boy rappers. I don’t even know the guy. I don’t know anything about him, except that he’s with Megan Fox.”
Machine Gun Kelly, whose real name is Colson Baker, was also asked about the alleged altercation but walked away without answering the question.
