I don't think she was fired. But it was fishy that she specifically told the media she was going to Italy just to hang out with her friends and watch filming because those are her favorite scenes from New Moon. Then, she says she's not going because she wants to spend time with family, which is suspicious because she's not close to her family at all (read the articles from her Thirteen days). And now, for her to be in LA and not go to the MTV Movie Awards when so many Twilight cast members were there... especially when it was obvious that Twilight would sweep the awards.
