Conor McGregor was involved in an altercation with Machine Gun Kelly on the red carpet at the MTV Video Music Awards in Brooklyn, New York, Sunday night. Sources tell TMZ that Kelly refused to take a picture with McGregor and the situation escalated from there.

When McGregor refused to back down on the request, Kelly allegedly shoved him, resulting in McGregor spilling his drink. Afterward, people nearby from both camps rushed in to prevent things from getting worse.
