Other mistake: In the scene where Paolo leaves the stage after everyone discovers that he can't sing, his bodyguard Serge stops him and Paolo suddenly loses his Italian accent. Paolo sounds very American when he says "You work for me, Serge."
Other mistake: At the graduation, when the girl says to Kate, "It's like watching those poor animals on the discovery channel," you can see Kate mouthing her lines.
Continuity mistake: In the scene where Lizzie's parents are seeing her off for her trip to Rome, she first walks away from her family after exchanging hugs and the legs of her pants are rolled up. She then turns around and walks back for a second hug with her mother and when she turns around and walks away from the family a second time, her pants are no longer rolled up.
Kate: How many Lizzies does it take to screw in a light bulb? Hmmm, I don't know, but it only takes one to screw up a graduation.
Trivia: When Ms. Ungermyer takes Ethen's headphones off he is listening to "Girl in the Band" by Haley Duff, Hilary Duff's sister.
Answer: No one knows for sure, but he likely lost his career and faced a lot of lifelong humiliation as have previously singers who were found to be secretly lip syncing to someone else's voice.
