Justin Bieber Says Instagram's For Satan

Justin Bieber says Instagram is Dante's Inferno of today, and he doesn't plan to plunge back into its pool of fire anytime soon.

The Biebs was performing in London Tuesday night, where he took a moment to reminisce on his days of snapping and posting ... which he basically says to hell with.

Listen carefully, he's still taking selfies -- not that any of us will ever see 'em.
