I'm not sure if you are referring to her music or just her in general as a person. It would really depend what you consider bad. Obviously you can't always believe everything you read in the tabloids etc.
no she is not bad people just make up stuff so she can look bad there just jelous. i like Miley shes always been my role model! and every teenager celebirty has too change i mean shes 18 now shes not 12
Miley is a teenager she has the right to express herself, she is not bad and she said she wanted to express herself. If your children copy her it's not her fault, she is no longer a child or working for disney. A lot of teen girls are like or worse than Miley but you don't complain about them because their not famous.
