See Justin Bieber Transform from 'Baby' Boy to Mustached Man
Remember when the world first caught Bieber fever? Some Canadian 14-year-old named Justin Bieber, with an angelic voice and a full head of hair — which would soon be styled in his famous swoopy 'do — entered the scene in 2007, after his YouTube videos went viral.
Millions of records sales; a high-profile romance with Selena Gomez; legal troubles (thanks to egg pranks and car races); a lot of tattoos; and some wacky outfits later, Bieber is still doing his thing. Although, now he's usually shirtless and wearing facial hair.
