There is no way she is singing with that cup or mike whatever it is stuck in her mouth most of the time !! All you have to do is blow up the picture and you can clearly see she's not singing it...unless she's a ventriloquist !! What are you trying to pull AGT ?
How can she be singing that if she's biting on the mike like she is and her mouth isn't even in sinc !! I call bogus !! Can't believe they want us to believe that's her singing that on stage !!
