Eminem is busy causing controversy again, this time with some disturbing lyrics about Iggy Azalea and Nicki Minaj.

An alleged snippet from Em's upcoming SHADYXV compilation album has leaked online, with the rapper name-checking both ladies on a track, reportedly called Vegas.

[related]While E! News and SPIN claim that Slim Shady's lyrics about Minaj are complementary, there’s no misunderstanding his dig at Azalea as he spits: “Put that s**t away, Iggy/ You gon’ blow that rape whistle on me.”

Here’s more from the verse:

You’re lucky just to follow my ride
If I let you run alongside the Humvee
Unless you’re Nicki
Grab you by the wrist, let’s ski
So, what’s it gon’ be?
Put that sh-t away, Iggy
You gon’ blow that rape whistle on me.

The song is a Bad Meets Evil track by Em and Royce Da 5’9 - with Em yet to comment on the alleged leaked Vegas snippet at press time.

Last week, Eminem hit the headlines after rapping that he would “punch Lana Del Rey right in the face twice like Ray Rice” during a SHADY CXVpher video with Slaughterhouse and Yelawolf to promote SHADYXV, which is due for release on November 24.

Rapper Azealia Banks later tweeted her support for Lana, writing that she would punch Em right back, adding: “Tell him to go back to his trailer park and eat his microwave hotpocket dinner and suck on his sisters tiddies.”

Both Iggy and Nicki are yet to reveal what they think of Em's track, but keep it MTV News UK for more...
