Once again, those that are role models to your children and grand children, continue to use poor judgement and in public, and act in a manner that can only be considered appalling. Perhaps it's time to consider additional guidance for your children, that would deny them access to what was once a good example, and now boycott anything related to them. It's also perhaps the only course of action that the entertainment industry will respond to... Loss of revenues. Don't support the industry or the actors/singers, their music or their tv/movies... Don't spend you money as a vote in favor for deviant behavior. They don't deserve your attention or monitory support.
Role model for your kids???
But don't rely on one persons opinion... Just check out YouTube. Everyone is appealed by her, excuse the phrase, performance. If she was interested in publicity, she got it. If she was interested in changing her image, she did it. If she planned to loose anyone's respect, she did it. Her own boyfriend didn't even attend... At least he's got some self respect. Think what you will... Act on what you feel.
