Forget Jay Z, Dr. Dre and Eminem ... the new king of diss rap is now ... Mariah Carey!!! Mimi's new song "Infinity" just dropped and she absolutely tears Nick Cannon apart. Talkin' 'bout you're madCould it be that you just lost the best you've ever had His fame: Boy you actin' so corny like FritosWouldn’t have none of that without me, though And his money: Is it lack of ice got you so cold?Have you ever felt this on your own?Why you tryin' to play like you’re so grown? Everything you own boy you still owe It wasn't long ago that Nick was leaving the door open for reconciliation ... but this song is the equivalent of her slamming that door in his face. And dead bolting it. And putting on the chain.
