Whoever got this tattoo must be a true Belieber. Justin Bieber is the original YouTube sensation; recordings of the once-innocent teen covering pop songs at home got him noticed and based on the popularity of his videos he landed himself a huge recording contract. Seemingly overnight, he was the biggest solo singer in the entire world. The crazy level of fan attention he got verged on hysteria at times and getting a tattoo of him definitely sits at the 'normal' end of the scale compared to what some have done to get his attention.
Bieber seemed to be developing a 'bad boy' reputation two or three years ago, although he appears to have calmed down again now, and he's started working with artists like Ed Sheeran to release songs that win him as much critical acclaim as they do from his screaming fans. This tattoo captures him in a more pensive, innocent phase; although he seems to have borrowed his hair from Elvis.
