I'm sure she had her reasons but I actually don't blame CZJ for not singing it all live, after all, for the majority of those that did the other night, their performances have been nothing but pulled apart and criticised across every form of social media. Maybe I've been looking in the wrong places, but besides here, I've seen very few ruffled feathers about CZJ lip-synching.
@peaches.... You must have follow the wrong friends on Facebook and Twitter, because everyone I know was talking about it the second after she exited the stage.
