Mariah, girl I love you but you know you're lying. Your ear-ins weren't the issue as seeing how I have seen several performances from you in which you have taken those things out your eye and still continued to sing with no problem. More so your dancers didn't miss a beat, so why couldn't you sing along? I know it's cold but you song there in the cold before and so have other singers. I know you know your songs and are creative enough to make up something on the spot, I've seen you do it before. You've been in the business 25+ you should know how to work through technical difficulties. And on another note this isn't the first time she's been plagued by playback errors. (Good Morning America Touch My Body) I am a Lamb but I'm not a delusional one, I'm not afraid to call Mariah out and try to sweep her wrongs under the wrong like they didn't happen. That's problem, Mariah's team and some of her fans keep treating her like she's some kind of child and tell her yes all the time. NO!!! She's a woman grown who will be 47 years old this March. Act your age not your shoe size.
