I don't think it'll damage her permanently. It hasn't seemed to bring her down TOO much. She is embarrassed, but at least she already put out an apology and will be making a public appearance tonight. They also showed her out partying on Saturday night right after the catastrophe.

I have no problem with the entertainers who lip synch if they have a good reason (such as strained voice or lots of dancing). I'd rather watch them lip synch and dance than just stand there like a dead fish and sing live.
