Richard Marx was NOT thrilled was a loud fan at his show this past week. In the video below, you can hear her screaming as he was singing his hit, "Angelia."
Marx wasted no time in letting her know she was out of order. When he finished the song, he lectured her, "I'm genuinely curious who raised you to think that anything you could yell out was more important than what we were doing." He then told her, "Learn some f***ing manners, lady!!!"
Richard was touring with Rick Springfield. Springfield supported Marx, saying, "I'm going to come to your work and I'm going to pee on your desk!!!"
