Clarkson has become a major star in the past year, with her hit "Since U Been Gone" earning both massive sales and critical respect, particularly from a rock community that has looked upon "American Idol" contestants warily. Her album "Breakaway" earned a Grammy nomination for best pop vocal album.He should appreciate that the show was able to put someone on a path to real credibility, but I suppose he doesn't like to think that the show's aura becomes a bad thing.
UPDATE: Looks like she backed down. Afraid of the bad press? I guess she hasn't really attained diva status.
