'Her people are really annoyed about the Casey Anthony comparisons,' a source told the magazine. 'Kristen wants that talk to blow over soon, because it looks really bad. She would never for no amount of money portray that girl. It's grossing her out. All those entertainment shows are doing polls and what not, and her people just want it to stop!'
