After all, he walked up to the stage to accept afan-votedhonor. He stood at the mic for a while looking befuddled before launching into his acceptance speech.
"I'm 19 years old, I think I'm doing a pretty good job and basically, from my heart, I really wanna say it should really be about the music," he said. "It should be about the craft, the craft that I'm making."
The Canadian singer added, "This is not a gimmick. I'm an artist and I should be taken seriously and all this other bull should not be spoken of. I wanna thank my manager, Scooter Braun. I wanna thank my family at home. I wanna thank my mother, my father, I wanna thank Jesus Christ. Mom, I love you so much. Dad, I love you. Little brother and sister, I love you so much. Thank you guys so much. Fans, you're incredible."
Bieber topped several other stars for the award, including Bruno Mars and Taylor Swift. He also took home the top male artist honor on Sunday night.
