The Evolution of Justin Bieber

In the three years since his Beatles-esque hairdo first graced our computer screens, Justin Bieber has done quite a bit of growing up. The progression is more apparent than ever when you consider the whimsical puppy-love plotlines of his early videos ("One Less Lonely Girl" centers around a charming treasure hunt with a smiling Bieber at the end) alongside the more mature and sexual vibes of his most recent one ("Boyfriend" puts on display the wooing of his oldest woman to date). In this video gallery, watch J.B. transform from an excitable, innocent kid into a bonafide adult with plenty of swag.
