Reportedly Mariah Carey fans were so upset with her that they booed her at an autograph signing for her new album E=MC2. The fans booed her because she was two hours late for the signing and some waited for eight hours to meet her last Thursday. She did the signing at Universal City Walk in Los Angeles and stopped signing and went home leaving her fans upset. Reportedly some of the fans booed and others thrashed their copies of her new CD and yelled profanities at her. It seems like even fans of the hollywood famous have mixed feelings about their singers and celebrities at times.
