Nick Cannon got pissed at Eminem after he rapped about getting Mariah Carey back in his song, "Bagpipes From Baghdad." "Nick Cannon better back the f**k/Up, I’m not playin’, I want her back, you punk/This is Hello Kitty bedspread satin funk/Mixed with egyptian with a little rap and punk." But the fight quickly turned playful when they took their beef to Twitter in an epic rap battle. I wish boys rap-battled for my affection! [Complex]
