I used to love her and almost semi stanned for her at one point as Stripped and B2B are flawless in every way. However then Bionic came and it sucked beyond belief followed by Lotus which I didn't even get through. Her voice has also changed a lot since giving birth to Max too, its like she lost 50% of her range and is left with a throaty, weak shadow of its former glory (Her voice was always throaty but it worked because of her range). I also find her to be a nasty person...Who knows maybe one day she'll turn me back around.
You don't know her on a personal level, so I don't think you can make these assumptions on her personality. I find it ironic that you stan for P!nk, whose known to consistently have a bitterness toward every other female artist. And isn't her voice what Xtina is most known for? The failed attempt.
