Back home, Matt browses the Internet and finds Italian gossip sites with pictures of Lizzie as Isabella. When he tells his parents, the family flies to Rome. At the airport, Gordo meets Isabella, who is upset that someone is impersonating her. She and Gordo realize that Paolo is planning to have a nervous Lizzie unknowingly sing live at the concert (as Isabella actually does), creating the impression that Isabella is a fake, which would damage Isabella's career and embarrass Lizzie. Gordo and Isabella rush to the concert to stop him. When Lizzie's parents arrive in Rome, Ms. Ungermeyer learns that Lizzie is missing. Ethan reveals that she is performing at the Italian Music Awards, and Lizzie's family and the class also rush to the concert. Backstage, Gordo and Isabella find Lizzie preparing for the show and warn her about Paolo's scheme. Lizzie refuses to believe them at first, but Isabella convinces her that Paolo is using her. Ms. Ungermeyer gets the class (and Lizzie's family) into the concert by pushing her way through the bouncers. During the performance, Isabella and Gordo expose Paolo (who is actually the one who lip syncs) by turning on his microphone, revealing his real voice. Embarrassed, Paolo runs off stage and is ambushed outside by paparazzi. Isabella introduces Lizzie to the crowd, and the two of them sing "What Dreams Are Made Of". When Isabella leaves the stage, Lizzie finishes the song solo, displaying a newfound confidence. Later, they all celebrate at the hotel's after party, where Ms. Ungermeyer rescinds Gordo's punishment. Lizzie's parents tell her she is grounded for the summer, but they still are proud of her. Lizzie and Gordo sneak away from the party to go up to the roof, where they promise to never let things change between them. The two kiss and then rejoin the party before they get into more trouble. The film ends with fireworks spelling "The End" and the animated Lizzie, doing a parody of Tinker Bell, winking at the audience. The film, produced by Stan Rogow, was directed by Jim Fall from a screenplay by Susan Estelle Jansen, Ed Decter and John J. Strauss, was filmed on location in Rome, Italy in the fall of 2002.
