Ke$ha who? :p
TBH, she isn't as popular as Britney Spears or Lady Gaga.
Just don't talk about her and she won't blow up in the pop scene. I mean how did abominations disappeared like Hilary Duff or Miley Cyrus in the mainstream world of music? The less you talk bout them, bad or good, the more they quickly fade away out of the face of earth...
