Eminem has attacked Mariah Carey and husband Nick Cannon in his new song, The Warning.

It is the latest episode in a long feud between the pop stars.

They first fell out when Eminem claimed to have had a fling with the chart star in 2001 – which she denied.

And she recently appeared to mock the rapper in the video for new single, Obsession.

On the new record, Eminem raps: “I got the exact same tattoo that’s on Nick’s back, I’m obsessed now, oh gee, is that supposed to be me in the video with the goatee?”

He then claims Mariah was “was wild ‘n’ out before Nick” and says he gave her “somethin’ to smile about”.

He adds: “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…

“Mariah, it ever occur to you that I still have pictures?

“But if I’m embarrassing me, I’m embarrassing you and don’t you dare say it isn’t true.”

It comes after Eminem sang about Mariah in his song Bagpipes From Baghdad, as well as her husband Nick.

In May, Nick leapt to his wife’s defence and blogged: “Homeboy is still obsessed with my wife”.

In previous weeks, the trio have denied any rift.

Mariah and Nick both say that the character in the Obsessed video is not Eminem, while the rapper says that his lyrics in Bagpipes From Baghdad were “misinterpreted”.
