Justin Bieber covered the first few lines of Lose Yourself at his concert in Detroit last night wearing the outfit he was planning to show off at the Blue Oyster Bar later that night.

When Eminem came up with Lose Yourself, I bet he never imagined a douchey 18-year-old twink named Justin Bieber singing it at one of his concerts. If he did, I’m 100% positive he would have went to college, completed a PhD in quantum physics, built a time machine and traveled to the future to beat the snot out of this little dweeb.

In other news, Justin Bieber went to Selena Gomez’s gypsy-themed 21st birthday party last week to give her a single red rose. Total Charlie Brown moment right there.
