Mariah Carey vs. Eminem
Mariah and Eminem were apparently smash buddies back in the late 90s/early 2000s. Something very wrong must have happened in the low-key fling (which Mariah still denies) because the two have thrown musical digs at each other ever since including Eminem’s “Superman” to Mariah’s “Clown” and “Obsessed.” In the latter song, Mimi even donned a faux Eminem get-up in the music video to show how insane Marshall was. Mariah’s hubby Nick Cannon joined the bout, challenging Slim Shady to a boxing match in 2010 for dissing his lady. Waaaay too messy!
