Eminem Trashes Lady Gaga and Justin Bieber in Latest Musical Diss-Fest

“Born This Way” songbird is “a male lady,” while “evil runs through” the “Baby” singer, according to “8 Mile” rapper's new song

Eminem has just given Lady Gaga and Justin Bieber a big "Kiss"-off as only he can.

The "8 Mile" rapper — who's famously taken aim at Christina Aguilera, Moby, his ex-wife, his mother and probably his neighbor's dog in lyrics past — has now targeted the "Born This Way" chanteuse and the "Baby" heartthrob with his laser-sharp tongue.

The one-two diss to Gaga and Bieber comes courtesy of "A Kiss," from "Hell: The Sequel," Eminem's collaborative album with fellow Detroit rhymester Royce da 5'9".

So what's his beef with Gaga? Oh, not much — Em just perpetuates the rumors that the singer isn't, from a strictly biological perspective, really a Lady. In the song, Eminem spits, "Tell Lady Gaga she can quit her job at the post office/she's still a male lady. Wouldn't f— her with her d— You heard it/The verdict's in."

Meanwhile, the rapper asserts that "evil runs through" cherubic popster Bieber, though Eminem also asserts that he "don't give a damn how Bieber doing."
