All-star rapper Eminem is picking his latest beef with Lady Gaga and teen sensation Justin Bieber. Is it just one way to hype his new record or does Slim Shady have a point. Has music gone to hell?

The diss is contained in the track “A Kiss,” off his upcoming EP Hell: The Sequel.

Slim rhymes with Bad Meets Evil partner Royce Da 5’9 and blasts Lady Gaga not for her music, but her sexuality.

“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*ck

You heard it

The verdict’s in.”

The rhyme plays off the rumor, since refuted that Gaga had a penis.

He also slams the Bieb, calling him a “demon,” saying without much elaboration that “evil seeps through him.”

Bieber professes to be very religious.

Singer Katy Perry also gets a name check.

“Aw hell Shady, he’ll tell it like it is

So Katy Perry, he’s on her tail

He’s tailgaiting.”

Wonder what hubbie Russell Brand thinks about that?

Eminem has beefed in the past with Ja Rule, Benzino, Everlast, the Insane Clown Posse and Canibus among others.

Eminem has even beefed with Royce, before having a falling out.

They teamed together on Tommy Boy records under the name Bad Meets Evil.

The team recorded such Hip-Hop classics as the Slim Shady LP rack, Bad Meets Evil, Scary Movies and The One.

By comparison, his shots at Gaga and Bieber are rather tepid.
