I think years of minions kissing his hairy arse went to his head. He can’t accept he was just part of a fad for a while, he thinks he genuinely became an A-list national treasure and everyone is in awe of his brilliance. When he looks at himself he sees all those comments from underage girls saying how hot he is, staring back at him. Really though... he was just another Zoella endorsement. When Zoe told her fans that this goofy animal was gorgeous, they believed her, just like they believed her over what was the best shampoo, or jumper from ASOS.
