R&B diva Mariah Carey doesn't need Nick Cannon to fight her battles when it comes to Eminem -- she'll do it herself. The 39-year-old recently released the song 'Obsessed' about a "delusional" acquaintance who won't leave her alone. Sound familiar?

Last month Em dropped 'his comeback album 'Relapse,' which featured 'Bagpipes over Baghdad,' a track in which he clearly calls Carey out, even pondering why their fling didn't last. If the rumors are true, Carey's 'Obsessed' makes the rapper look as though he imagined the alleged "fling."

"I was like,'why are you so obsessed with me?'" Carey asks as the song begins. From there the lyrics run suspiciously close to her alleged encounter with Em. "All up in the blogs/ Say we met at the bar/When I don't even know who you are/Say we up in your house/Sayin' I'm up in your car/ But you in LA, I'm out with Jermaine."

Then things get even more interesting. "I'm up in the A you're so so lame/and no one here even mentions your name/It must be the weed, it must be the E/cuz you be poppin', hood, you get it poppin.'" (Em has talked about his drug addiction to prescription pills resulting in two stints in rehab.)

As the hook drifts in and out, Carey throws a little reverb on her voice as she continues to confront her stalker. "Ooh boy why you so obsessed with me?/Boy I want to know- lyin' that you're sexin' me/when everybody knows it's clear that you're upset with me."

Carey never publicly addressed Em's lyrics in 'Bagpipes over Baghdad' in which he threatened her husband and stated that he "wanted her back." Cannon did not find the song the least bit entertaining and took to his blog to threaten Em with, of all things, a rap battle.

'Obsessed' is currently streaming on Carey's website. The songstress is set to release her latest album 'Memoirs of an Imperfect Angel' later this year.
