He is ignorant. He should have been stopped in his tracks and escorted out. If I were her mom and my teen daughter was winning an award like that and he did that to her... I can tell you it wouldn't have been pretty. How dare him interrupt her acceptance speech.
He should be banned from these award shows and maybe radio stations should ban him too. He's a jerk. Now everyone knows it. She is one class act. And Beyonce what a stand up lady. I applaud her.
