The majority of people in the world were shocked by Miley's routine at the VMAs Sunday. A lot of it has to do with the fact that she was a former Disney star so therefore people still look at her as Hannah Montana. What people need to understand is....she is 20 years old!!!! The girl is legally an adult which means she went through her teenage phase already and now she wants to be known as a rebel and do her.
This is a really big issue in the entertainment world when it comes to child stars. People get used to a celebrity looking and acting a certain way that when they finally grow up it's automatically controversial. Everyone is not going to be kids forever. Did she go overboard by making her performance too raunchy? Maybe so, but she is an adult and she feels like she can do what she wants and at this point in her life she feels free and she is just simply expressing herself. Her dad even took to twitter showing some support to his daughter and realizes that she is just finding herself.
The show is over and she is not the only one that twerks. At the end of the day she still has a fan base.
