Charlie Puth, up until a few years ago, was an unknown entity in the world of pop music. While Justin Bieber had shot to worldwide fame and Taylor Swift had already released her second album, Charlie Puth was still getting his pieces together to get a scholarship to Berklee School of Music. But since his record label signing with Ellen DeGeneres, the New Jersey-born pop star has steadily grown in stature, finally having announced his arrival to the world with Wiz Khalifa's single "See You Again".
