No big deal. I’ve worked as a professional singer, and there’s a big difference between actually singing and making just enough sound to lip sync realistically.

See, when you lip sync, if you don’t actually make any noise, it’s obvious that you’re not singing, because your throat doesn’t move. If you make even a little noise, basically just half-speak the words, your throat moves enough that it looks like you’re singing.

She’s not _trying_ to sing here, because nobody (supposedly, anyway) is going to hear what she’s doing, so it doesn’t matter. She’s concentrating on how she moves and looks, not how she sounds. IF she were live mic’ed she would really sing — and even if she doesn’t sound like the album , she would be a hell of a lot better than that.

They can do a lot in a studio to make you sound better than you are, but don’t imagine for a moment that what you hear on this video is even close to what she’s capable of.

In fact, if she really belted it out every night she would probably do some damage.
