Eminem has spent roughly 65 percent of his legendary career making fun of famous people. It could even be said that you’re not truly a pop-culture icon until Slim Shady takes you down a notch—though that doesn’t necessarily mean you’ll stay famous, as Chris Kirkpatrick can attest.

So it should come as no surprise that Mr. Mathers has taken aim at Lady Gaga on one of the tracks for his forthcoming album Hell: The Sequel (a tag-team effort with Royce 5’9″ under the name Bad Meets Evil).

On the song “A Kiss,” Em spits the line “Tell Lady Gaga she can quit her job at the post office/ She’s already a male lady/ Wouldn’t f— her with her d—/ The verdict’s in.” Check out the song here:

Of course, like his long-stale jokes about Christopher Reeve, Em is a little bit behind the times; nobody has accused Gaga of being a dude in almost a year.

As you can hear, Eminem also has some choice words reserved for pop’s boy-diva Justin Bieber, rapping, “Him don’t give a damn about Bieber, do him?/ Evil just seems to be seeping through him.”

It seemed like it was only a matter of time before Em jumped on the Canadian superstar, though we were hoping for something a little more scathing, a la the infamous Moby beatdown.

So here’s a question: What celebrities should Eminem be taking on? There could be a whole TV show surrounding it, like a reverse version of H8R. But we turn it to you first, EW commenters.
