Chicago rap mainstay Lil Durk turned a lot of heads by releasing “Broadway Girls,” a song with Morgan Wallen, the rising country star who has become a polarizing figure since being caught on video using a racial slur a year ago. Durk, who has been enjoying the biggest success of his career, is not backing down from the Wallen association. “He ain’t no racist.” Durk recently told TMZ. “That’s my boy. We had a long talk. He had his public situation… I vouch for him and he good.” As if to underline that sentiment, Durk has welcomed Wallen onstage with him — at an MLK-related event, no less.
