We're sure that Justin Bieber receives his fair share of fan art. We don't doubt that some of it's raunchy, like the image of a brunette Belieber, nestled naked in his arms while in bed, under the 'Justin Belieber' caption. We expect that. We're sure he does, too.
But it was totally irresponsible of The Biebs to share it on Instagram, to tons and tons and tons of followers.
