Tekashi 6ix9ine's constantly causing some sort of controversy. Whether it's his gang affiliations or his big mouth, there's always someone who's trying to test him. However, the fact that he's fearless in the way he speaks is similar to 50 Cent's come up. So it should come as no surprise that 50 Cent's riding for the Brooklyn MC in the midst of all of the beef he's involved with.
The argument of who's actually the King Of New York has gone on for a long time. Jay-Z and Diddy are the most obvious choices for the throne but it's recently been sparked up in the new generation because of Tekashi 6ix9ine's claim to hold that title. Earlier today, 6ix9ine posted a video alongside 50 Cent and it looks like 50's co-signing 6ix9ine's claim.
"Tell 'em what you runnnin'! Tell 'em what you runnin'!" Fif says before 6ix9ine says, "New York is mine, man."
To an extent, the 50 Cent co-sign seems to validate what 6ix9ine's been saying. However, 50 Cent is just as much of a troll as 6ix9ine so there's a clear aspect of this that's meant to rub people the wrong way.
Maybe this might spawn a collaboration between the two in the near future. 50 Cent's previously said that Street King Immortal is dropping this year so maybe we can expect a guest appearance from 6ix9ine.
