Justin Bieber Says He's Not a Robot

Justin Bieber waxed borderline poetic Saturday night, explaining to his audience what they see onstage is the real deal ... flaws and all.

Justin's "Purpose" tour rolled on in Scotland, where he scoffed at various reports that he was flying off the rails by demanding that his crowd stop screaming and listen when he talks.

He sounds genuine in the clip, explaining he wants to help people who are listening to him and actually celebrating his missteps ... which he says makes him human.
