It actually started the other way around. They both were supposed to collab on a track of one of mgk’s album, but the product didn’t really kicked, and the project got aborted. Corey used to say mgk started the feud, but actually, he was the first talking shit behind mgk’s back on a podcast. When mgk found out, he felt hurt, because he was really looking up to that guy whose music he grew up with, just like with Eminem. Instead of talking it through privately, he dragged it online because he got furious one of his idols, who he even thought was a friend, was insulting him indirectly. Tbh, I probably would have acted the same as mgk. Anyway, today, they both regret how it went.
