EMINEM AIR'S OUT MARIAH'S DIRTY LAUNDRY!

Eminem, miffed that Mariah Carey impersonated him in her latest video, "Obsessed," retaliated this week with the musical equivalent of an atomic bomb - a track that purports to reveal nasty details about their sex life (the rapper claims they had a relationship; she has long denied it) that would make Paris Hilton's sex-tape videographer blush.
He also threatens to release photos and voice-mail recordings that, apparently, he has been holding onto all this time (obsessed, much?).

The back-and-forth will go down in the celebrity feud pantheon as the meanest of all time.

And the lesson here is twofold: Don't ever, ever date Eminem. And celebrities, resist the urge to air your vicious rivalries and dirty breakups in public.

Public feuds are so high school.
