Lady Gaga has joined the ranks of Britney Spears and Christina Aguilera as the newest female pop star to be brutally dissed by Eminem. But while in the past Em has expressed his desire to sleep with (or rape) hot singers of the moment, with Gaga, he claims she already has a wang between her legs.

Slim Shady has joined forces with former collaborator Royce da 5’9″ to form a group called Bad Meets Evil, and yesterday they revealed a track that name drops Katy Perry and Nicki Minaj (they’d like to sex ‘em both). But the song, entitled “A Kiss,” saves it’s harshest line for Lady G. “Tell Lady Gaga she can quit her job at the post office/She’s still a male lady,” Marshall raps. That’s mean. And hilarious. Sounds like Eminem’s back to his old self. Thank god, I was sick of the inspirational crap about not doing drugs.
