Yikes, I'm NOT a fan of this one. I hate how she's affecting her voice in these live performances. You can especially hear it in the bridge. That's NOT what her voice naturally sounds like, and I think it's worse.
And she does look tired, but cracked-out? My guess is these are fans of artists who used to compete with Vanessa and there's residual bitterness or something. Because she definitely looked tired, but I wouldn't go tweeting about it to the masses lol
