Remember when Justin Bieber was a fresh-faced teen singer with that hit song "Baby" you couldn't quite get out of your head once you heard it? The Canadian pop star turned bad boy in 2013, seemingly making news for all the wrong reasons at nearly every turn. His year started off TMZ posting photos allegedly showing him smoking marijuana and 2013 only went down from there. The rest of his escapades included leaving a comment in the Anne Frank House guestbook suggesting Frank would have been a "Belieber" if she had lived, urinating into a mop bucket while insulting Bill Clinton, attempting to sneak his pet capuchin monkey into Germany, getting into fights with paparazzi, having his bodyguards carry him up the steps of the Great Wall of China, allegedly hitting up Brazil's legal brothels while on tour, spraying graffiti on the walls of an Australian hotel, and apparently misplacing all of his shirts. And to top it all off? He also lost his title of the celeb with the most Twitter followers to Katy Perry in early November. Ouch.
