Whenever Eminem drops a verse, controversy isn't too far behind. An alleged leak from the upcoming SHADYXV compilation has surfaced, and it has Em referencing Iggy Azalea and a rape whistle. The audio is rough, but it definitely sounds like Marshall Mathers.

According to the YouTube video, the line in question comes from the Bad Meets Evil (Em and Royce Da 5'9) track "Vegas." MTV News has the lyrics from the song going as follows:

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 reference to Nicki Minaj and skiing could mean tons of things. The Azalea line seems much more confrontational. Now, we're not 100 percent sure that this is a legitimate leak from the album because nothing has been confirmed by Em's camp. But the verse would match up to some words he rapped in last week's "SHADY CXVPHER" video when he said he would "punch Lana Del Rey right in the face twice like Ray Rice."

SHADYXV spans two discs and 28 tracks with a laundry list of artists. It is out Nov. 24.

"So we were like, alright, we want to get something out this year 'cause it's the 15th anniversary of the label, and then it dawned on us that this would actually be the 15th project we'd be releasing, which just sort of lined up nicely," Em's manager said about the release. "So we thought it would be a good time to go back and do a retrospective on the 'greatest hits,' quote unquote."
