The 2013 Billboard Music Awards were bittersweet for Justin Bieber. He nabbed the coveted Milestone Award, but the crowd didn't make it easy for him to accept.

Rocking aviators and going onstage to a mixed chorus of boos and Belieber shrieks, it was an intense moment for Bieber. He looked around silently for almost a full minute. After getting encouragement from presenter Cee Lo Green, Bieber began to speak, but his voice was shaky and breaking at times. "I'm 19 years old," he said firmly. "I think I'm doing a pretty good job."

That garnered more cheers. "From my heart, I really just want to say, it should be about the music, the craft that I'm making," he said. "This is not a gimmick. I'm an artist, and I should be taken seriously." Amen, brother! "I want to thank my manager Scooter Braun, my family, my mom, Jesus Christ," he continued. (Jesus earned some strong cheers.) "Mom, I love you so much, Dad I love you so much, my little brother and sister, I love you so much -- my fans, you're incredible."

It was an overwhelming mix of pride at his accomplishments and hurt at being vocally reviled by a large portion of the crowd on national television. C'mon, crowd -- have a little class. Haters gonna hate. Host Tracy Morgan addressed their rudeness: "Don't be booin' nobody up in here," he scolded. "This ain't the Apollo!"
