Mariah gets revenge.

Mariah Carey Gets Revenge, Dresses Up as Eminem

Mariah Carey is out for revenge against Eminem.

Dressing up in drag as the rapper while filming the music video for her song "Obsessed" in New York City, the singer took their feud to a new level.

The Mariah Carey tune's lyrics include this line:

"You're so lame. Ooh boy, why you so obsessed with me? Ohh finally found a girl you couldn't impress / Last man on the earth / still couldn't get this."

Ohh, snap. We have to say, her costume designer did one heck of a job.

Here's Mariah and the real Eminem. Who do you think is more hard core?

Mariah Carey channels her inner Eminem. It's a pretty accurate depiction.

This is in response to when Eminem rapped about Mariah Carey - who he has said he briefly dated in 2001 - in his song "Bagpipes From Baghdad."

In that song, Eminem raps, "Mariah whatever happened to us. Why did we ever have to break-up? Nick Cannon, you better back the f**k up. I'm not playing, I want her back, you punk ... I wish you luck with that ... wh*re!"

Those lyrics prompted Carey's husband Nick Cannon to respond: "What type of grown... man lies about getting with a chick? Only Slim Lamey! LOL!"

Bet Eminem is still stinging inside and lying awake at night replaying that retort. He did admit later that he went too far in that song, at least.
