Okay I was Reading about Princess Charm school and I realized there is another similarity, The Crown of GARDANIA (and kingdom i think) and the Magical Diamond Plant of GARDANIA in Barbie Princess and the Popstar, i think there is a connection with these cause the Plant of Gardenia keeps the Kingdom of Mirabella alive and Like Barbie the pearl Princess and Rapunzel they are unaware of their Royal identity, and in those Movies whomever the true heir the crown/ crest ECt will glow/ transform them, i believe Princess and the Popstar and Princess charm school have some sort of Connection (It would also explain why Sophia (Or Blair) is wearing a extremely similar dress from princess and the popstar, lemme know what u think about the Gardania situation
