Nope. It's only on ATRL where I've seen pathetic low-lifes jump on the hate bandwagon because they're insecure and unfulfilled with their own lives. Pretty sad, if you ask me.
She isn't even known that much to be hated. True hated singers are people like Justin Bieber, Lady Gaga (questionable) or Miley Cyrus.
I don't see why ATRL hates on her. She isn't that interesting (to me) to spend that much energy on
