In 'The Princess Diaries 2', Mia Thermopolis is now a high school graduate and on her way to Genovia to take up her duties as princess (contrary to what was presented at the end of the first film, Mia does not leave her home for a few more years). Her best friend Lilly also joins her for the summer. Mia continues her 'princess lessons'- riding horses side-saddle, archery, and other royal. But her complicated life is turned upside down once again when she not only learns that she is to take the crown as queen earlier than expected, but that she is also to be married before this event. Robert Schwartzman will not be reprising his role as Mia's love interest.
