Eminem has threatened to leak nude photographs of Mariah Carey.

The rapper
has released a track called 'The Warning', which blasts the 'Fantasy' singer and her husband Nick Cannon, and threatens to expose the brief relationship they had in 2001 by making public intimate pictures and voice mail messages.

The song
comes after Mariah appeared to dress up as Eminem in the music promo for 'Obsessed', in which she said he was "delusional" for hinting they had slept together in his track 'Bagpipes from Baghdad'.

He raps in 'The Warning': "Only reason I dissed you in the first place is because you denied seeing me. Now I'm p***ed off. I'm obsessed now. Oh gee, is that supposed to be me in the video with the goatee?

"B***h, shut the f**k up before I put all them phone calls out you made to my house. How many times you fly to my house? Still trying to count. Better shut your lying mouth if you don't want Nick finding out. You probably think since it's been so long if I had something on you I woulda did it by now. On the contrary, Mary Poppins, I'm mixing our studio session down and sending it to mastering to make it loud. Enough dirt on you to murder you. Mariah, it ever occur to you that I still have pictures?

"Call my bluff and I'll release every f***ing thing I got including the voicemails right before you flipped your top.

"It cuts like a (knife) when I tell ya get a (life). But I'm movin' on with mine. Nick, is that your wife. Well tell her to shut her mouth then I'll leave her alone. If she don't then I'm just gonna keep goin."

He goes on to describe intimate details about their sexual exploits, mentions her by name several times and brands her a "w***e" and "alcoholic".

Following Eminem's original comments in 'Bagpipes from Baghdad', Nick jumped to his wife's defence, claiming "homeboy is still obsessed with my wife".

He added: "I realised that this so-called man has just disrespected... one of the world's most significantly influential artists, one of the most notable black females of our time, the incredibly cherished, globally loved and world-embraced woman of colour, Mariah Carey."

Mariah herself spoke out about 'Obsessed', insisting she wasn't attacking Eminem in the video.

She said: "Everybody started having their own speculations about who the stalker in the video was. When I look at that stalker and me with the beard, I look like my brother and my cousin Chris. So basically, you know, all the speculation about who I'm playing in the video, it's not accurate."

Meanwhile, it has been claimed Mariah sleeps in a Cinderella carriage.

The singer is a huge fan of the rage-to-riches fairytale - in which the downtrodden heroine rides a horse-drawn coach her fairy godmother creates from a pumpkin - and spent over £60,000 for an interior designer to create a replica with a bed inside.

A source said: "She identifies with it because people were hard on her when she was younger."
