Justin Bieber Wants Us To Believe He’s Not A Robot

Justin Bieber appeared on David Letterman’s show last night to plug his new film Never Say Never. During his time in the hot seat, Biebs tackled the normal subjects of fame, his Twitter obsession and how Usher helped him become the star he is today. But then he also wanted to reiterate the fact that he’s a real human boy.

“People might think that some people just made me … they put me together, like a machine,” he explains to Letterman. “But [the movie] shows I really worked hard to get here.” Also, a robot’s voice doesn’t change because of puberty. Robots don’t have puberty. FACT.
