Actually that's only been going on for about 5 years. And 5 years for this kind of transformation is a shockingly short time. Like i said, he set a new high bar for other teen idols to reach and i hope they never reach it. In those 5 years he went from an innocent teen to a celebrity of Osbourne levels, and Ozzy himself needed a few decades to pull that off. As far as i'm concerned, he doesn't need to be deported to Canada. As long as his parents slap him in the face, pull him off the stage, tell him to move into their basement and ground him for a couple of years. He's 19 ffs.
Don't compare Bieber to Ozzy. Ozzy has actual talent, has been relevant for decades, and will continue to be relevant for years to come. Spoiler: Language [YOUTUBE]_Fuitsj37UI[/YOUTUBE]
I'm pretty sure both lines would be equal in length. Besides, 12 year old girls stopped liking him once he stopped sounding like one.
