I don't even care for Avril, but this is so stupid and petty. He's too middle-aged to be acting like this. I don't think it's a good idea for him to be so unprofessional on twitter when he works in the entertainment industry. It would be different if he was just a random blogger. I wished Taylor hadn't revived his career and hope she drops him soon. He's gotten even more obnoxious since she started using him.
