Eminem vs. Mariah Carey

The famous rapper has made several digs at Carey through a number of songs, beginning as early as 2002, after having a fling with the pop star. Though Carey has repeatedly denied any relationship with Eminem, the two have continued to toss insults back and forth via song lyrics, with Em's friend 50 Cent and Carey's husband, Nick Cannon, both getting involved. Guess money can't buy you maturity.
