Just who’s responsible for Mariah Carey’s horrible performance on “New Year’s Rockin Eve”? A great deal of finger pointing is going on. According to TMZ, the singer believes Dick Clark Productions, which produces the show, deliberately sabotaged Carey’s performance. Carey allegedly went to show producers to inform them that her earpiece wasn’t working, only to be told that the matter would be resolved before show time. Her microphone battery was replaced and she prepared for the show. While preparing for the show, Carey became alarmed when she discovered her earpiece hadn’t been repaired. She was also given an opportunity to do a soundcheck, but alledgedly refused and had a stand in do a soundcheck in her place. Dick Clark Productions is considering suing Carey for defamation. We’ll have to wait and see what transpires.
