Every little girl (and some little boys) loved Hannah Montana when it was a top rated show on TV. The idea of being a rock star or celebrity in disguise, and then getting to be a regular girl too is just too fun.
You can also decorate any cake of your choice with Hannah items, easily found at any party store!
This idea for a Hannah Montana Party was shared by one of our site visitors:
Have a Hannah Montana look alike contest and Hannah Montana decorations. Have her music playing the whole time and gift baggies with her stuff.
