Conor McGregor and Machine Gun Kelly appeared to have gotten into an altercation at last night's MTV VMAs.
As reported by TMZ, the 33-year-old UFC icon approached the 31-year-old rapper on the red carpet in the hopes of saying hello.
According to a source, the Irish fighter "stuck his hand out and started walking up to the singer". As video footage shows, MGK - real name Colson Baker - then says something, before his security guards start to push McGregor away.
Check out footage of the incident below:A source also told the outlet that McGregor had wanted a photo with the 'Bloody Valentine', however, a spokesperson of McGregor told The Independent: "Conor McGregor did not ask anyone for a picture, nor did he instigate this incident. He does not know Machine Gun Kelly, outside of the fact that he attended Conor’s fight this past July."
Either way, things quickly heated up when McGregor spilled his drink and dropped his cane.
McGregor responded by allegedly throwing what was left of his beverage at MGK. Photos show McGregor reaching for the rapper, as security holds him back - preventing the two from coming to blows.
A source who was allegedly at the scene told Page Six: "They scuffled then it settled down and Conor went for him again."
Page Six adds that things quickly calmed down, and MGK walked the red carpet with girlfriend Megan Fox - putting on a passionate display for the cameras:
The alleged scuffle comes as quite a surprise, especially considering MGK was previously photographed attending McGregor's UFC 260 fight in Los Vegas back in March.
A physical altercation may not have been the best idea for the former champion, especially considering the fact he suffered a nasty leg injury against Dustin Poirier at UFC 264 in July.
Warning - this footage is not for the faint-hearted:But despite walking the red carpet with a cane, McGregor looked great on Sunday night at the Barclays Center. Donning a pink suit, he continued to walk the red carpet alongside girlfriend Dee Devlin.
Later in the night, MGK was joined on-stage by frequent collaborator Travis Barker to perform 'Papercuts'.
