The last move in this back and forth between Eminem and Mariah Carey was made by the songbird, with the release of the music video for her single, “Obsessed.” And as she must have known that he would, the perpetually angry rapper is responding with a diss track of his own, “The Warning.”

In it, Em cautions his supposed former lover, “You probably think since it’s been so long if I had something on you Iwoulda did it by now, on the contrary, Mary Poppins, I’m mixing our studio session down and sending it to mastering to make it loud, enough dirt on you to murder you, this is what the f–k I do…”

Later on, Eminem goes on to say, “Mariah, it ever occur to you that I still have pictures?”

I wouldn’t worry too much if I were her. She once had a spell cast in New Orleans, so that every picture of her be magically photoshopped to look like this.
