Former UFC two-weight champion Conor McGregor attacked American rapper Machine Gun Kelly on the red carpet of the Brooklyn show.
As the journalist Mark Raimondi reports on Twitter, McGregor threw a glass with a drink at the musician. After that, security intervened in the situation.
The reasons for the quarrel were not disclosed.
Recall that in the last fight, McGregor lost by technical knockout to American Dustin Perrier. The Irishman broke his leg and the fight was stopped by a doctor.
