Slim Shady, a.k.a Eminem is back to tracking disses. In his latest work, Em takes a jab at tween sensation, Justin Beiber -and who would've guessed it , Lady Gaga. In the new track off the upcoming "Hell: The Sequel" album with Royce da 5'9, Em (famous for comical disses and slamming pop stars) plays on the old hermaphrodite rumors.

"Tell Lady Gaga she can quit her job at the post office,she's still a male lady. Wouldn't f **ck her with her d**k,You heard it.The verdict's in."

As far as Biebs goes- "evil runs through him," according to Em.

There is also mention of Katy Perry in the track, but nothing offending.

Along with the new album, Eminem is also working on a new a movie to be titled southpaw; an action flick about a boxer tring to get back into the spotlight. Antoine Fuqua, "Training Day" director, is currently negotiating a deal to direct the feature.
