This movie finds Barbie as Princess Courtney, a modern princess that is getting ready to go to Camp Royalty for two weeks with other young Royals. We also find young and hot, new Popstar named Erika getting ready to head out to Camp Pop with other budding young Pop stars, Country stars and Rock stars for the same two weeks. BUT! All is not as cool as these two girls think it will be and both of their worlds gets turned head over heals and each ends up at the camp of the other and they are forced to learn to deal in the world of the other while making new and unexpected friends along the way. But when something happens to make one or the other camp shut down for good, the two girls and their new friends hatch a musical plot to save both camps. Lots of good music, people learning that no matter if you are Rock or Royal, the two worlds can mix with some great results and that no matter if you are Rock or Royal, friendship with each other crosses the boundary of each world and that they both do indeed mix very well! Personally, the song "What if I Shine" is one of the best songs in the movie and it is easy to sing along with either of the girls. You will be laughing and singing through the entire movie. I would recommend this movie to every one and tell them to clear the floor in front of the TV because you and your children ARE going to be dancing to the music by the time the movie ends!
