The singer's manager Benny Medina publicly derided the rapper, who is in hospital battling his addiction to sleeping tablets, and ridiculed his waning popularity.
Carey reportedly remains furious with the rapper who used intimate answerphone messages from her to accompany his song YOU MAKE ME SICK during his Anger Management III tour.
Medina tells the New York Post, "While we appreciate Eminem as an artist, lately his work has seemed tasteless and unnecessarily mean spirited. The public seem to agree, just look at his declining record and concert ticket sales."
The answerphone messages heard Carey begging, "I heard you're getting back with your ex-wife. Why won't you see me? Why won't you call me?"
