Justin Bieber’s concert tour made a stop in Detroit on 28 July 2013, Eminem’s old hood. The Biebs decided to show his respect for the rapper by performing ‘Lose Yourself’ on stage.
Apart from messing up the first line with “his palms are heavy”, when the lyrics are “his palms are sweaty”, the fans went crazy for the performance. But then again, we don’t imagine Justin and Marshall have much in the way of a shared fan base.
