The Princess Diaries 2: Royal Engagement
Before the wedding, Joe informs Mia and Peter that Nicholas is innocent. While walking up the aisle Mia suddenly stops and charges out of the church. Queen Clarisse and Peter follow and Mia says she doesn't want to marry because of the law. Clarisse encourages Mia and Peter to follow their hearts, something they have never done and has now cost her Joe, the only man she truly loved. Mia and Peter re-enter the church, and after pointing out how their grandmother has ruled Genovia while unmarried for a number of years, she tells the members of parliament in the audience to consider the significant women in their lives and questions if they would have them do what they're trying to force her to do (marry someone she does not love). Mabrey cites the law again and once again suggests that his nephew be named King, but just then, Nicholas not only refuses the crown, but also disowns Mabrey as his uncle. Mia and Peter propose the law on royal marriages be abolished, and the Parliament unanimously gives its assent. Encouraged by Mia and Peter to have their own happy ending, Clarisse proposes to Joe and they are promptly married.
