"Eminem heard that Kendrick Lamar was the best rapper and he invited him to the studio to get him on a song,"explainedSheeran. "He arrived, and Kendrick came with all his mates and Eminem said, ‘I just want you in the studio, just you on your own and then my engineer is gonna come in and then record you doing it, but your mates aren’t allowed in.’ And then,Kendrick did it and wrote a sick verse. And then everyone came in to listen to it and Eminem said that he did it to test Kendrick, because he thought he had a ghostwriter.
