The Princess Diaries 2: Royal Engagement.

Mia Thermopolis is now a college graduate and on her way to Genovia to take up her duties as princess. Accompanied by her friend Lilly, Mia continues her 'princess lessons', like riding horses side-saddle and archery. But her already complicated life is turned upside down once again when she learns that she is to take the crown as queen earlier than expected, all while she meets a mysteriously charming young man.
