"Tell Lady Gaga she can quit her job at the post office/ She's still a male [mail] lady, wouldn't f--- her with her d---/ You heard it, the verdict's in," Em raps on the Bangladesh-produced banger.
In the interview however, Slim Shady backed away from his 'A Kiss' lyrics, explaining that the diss was just "a joke," and referred to the 'Born This Way' singer as "an incredible talent."
"I think Lady Gaga, as an artist you know, she's undeniable," Em said earnestly. "That ['A Kiss'] was one of them things where sometimes I get a joke in my head, and I kinda want to share it with the world, you know what I'm saying? So it was just one of them things man. You know, it's all in fun, its hip-hop. It is what it is, but as far as an artist, she's dope, she's an incredible talent."
Eminem and Royce are two of hip-hop's most contentious MC's, even having dissed one another, when they were on bad terms, but Em's list of rivalries is unparalleled; having engaged in battles with everyone from Mariah Carey and Nick Cannon to Moby, Insane Clown Posse and Limp Bizkit.
Em and Royce's Bad Meets Evil EP 'Hell: The Sequel' is in stores today (June 14).
