The 19-year-old singer was waiting for girlfriend Selena Gomez at the Toronto airport when some of his fans approached asking for autographs, but Bieber refused because the people were being impatient, reported Contactmusic.
"Do I not have any right as a human being to wait for my own girlfriend? Why do you have to be so impatient? I've been here waiting for my girlfriend.
"I'm still a human being, I have a right to wait for my own girlfriend. You're not being very respectful at all. I feel very disrespected with all you guys waiting. You say you're really my fans, but then why are you doing this.
"I've had a long day, I flew in. I don't have to be nicer about it. You guys are in my face," he said in a video posted on his blog.
