MGK and Yelawolf previously threw jabs at eachother late last year, but both then said there's no issues. Now they're back at each other's necks. In a Shade 45 interview last week, Yela told Rude Jude and Lord Sear  that "probably the most insulting thing on the planet, is to be asked to sign a Machine Gun Kelly autograph.” MGK responded on the red carpet at the BET Awards last night, calling Yela an old man. Oh boy.
