i have never liked her singing, nor her performances... the last time i saw her perform was a few months ago with a handful of other artists... i thought her performance was awful... a lot of screeching and yelling...
The one and only time I ever saw her "perform," she came back to American Idol as a guest. Her "performance" was so bizarre, and so awful, that the camera panned to Simon Cowell, who had a disbelieving, horrified expression on his face. She must not have sung that way during the competition, or else I can't imagine how she won.
