Justin Bieber has grown up so quickly over the past few years.
Bieber first got his start when he was discovered only four years ago on YouTube by Scooter Braun.
Since then, Justin Bieber has sold more records than one can count, sold out hundreds of shows across the world, and caused mass hysteria amongst almost every teenage girl in America.
Over the past few months, Bieber's been transitioning into adulthood with new hip-hop inspired records and his new rapper friends.
He took his new image to a whole new level when he walked out with professional boxer Floyd Mayweather during the MGM Grand-hosted Floyd Mayweather Vs. Miguel Cotto fight in Las Vegas over the weekend.
GlobalGrind decided to go back in time and exhibit the evolution of Justin Bieber. From My World to the Money Team, Bieber has transitioned into a handsome young man.
