Eminem’s new album 2013 is still in the recording stage and last weekend gave one of the best examples of why, as Eminem’s hype man, Mr. Porter, has said, you shouldn’t “rush art.” This weekened Justin Bieber tried his hand at rapping, chose the Eminem song “Lose Yourself” and promptly forgot all the lyrics. Eminem has blasted other celebrities on record for much less. Just ask Katy Perry or Lady Gaga. Eminem fans can now hold out hope that Slim Shady will immortalize the Detroit dis on his new album.

Justin Bieber’s song choice, “Lose Yourself,” was off the soundtrack to Eminem’s hit movie “8 Mile.” At Justin Bieber’s Sunday night concert in Eminem’s home town, Selena Gomez’s boyfriend showed why the Bieb is still learning to rap. He may play dozens of instruments, but shouldn’t paint himself a shade of Eminem while playing the Motor City.

Justin Bieber’s rap cover of the Eminem hit only lasted 25 seconds, but the audience at a sold out show at the Joe Louis Arena in Detroit, Michigan, on July 28 who came to see his “Believe Tour” found a reason to disbelieve. Eminem should at the very least, take a page out of Nicki Minaj’s book and put a restraining order on The Bieber barring him from attempting an Eminem tribute. Or mockery. Maybe this is why he can't keep it together with Selena Gomez. Maybe there should be a restraining order keeping the Bieb miles away from rap in general. The Bieb didn’t know the lyrics. The 19-year-old singer has long boasted his love of rap, but he couldn’t even get through the opening lines of the 2002 hit.

Eminem has already lashed out at the Bieb in his 2011 “A Kiss,” rhyming “Him don’t give a damn about Bieber, do Him? / What a demon, a behemoth, evil just seems to be seeping through him.”

After his 18-song show, Bieber told the 20,000 people assembled, “Thank you for believing in me. And I believe in you!”

But Eminem fans still can’t believe what Bieber did to the song.

Eminem’s new album will come out some time later this year. He’s done some work in the meantime on albums by Skyler Grey and Big Sean. He also announced a mini-tour of Europe. Hear the real thing. Here are the dates.
