It's basically about a boy who's in a boy band. Something happens with the band and the manager, he decides he doesn't want to do it or something, I don't know, then he runs away and ends up staying with this girl who is a fan of the band. She hides him in her house and they end up falling in love. He takes her to her prom and is recognised and he ends up getting taken back on tour with the band. They get reunited at the end, kisses, yadda yadda yadda. I remember her wearing a checkered dress to her prom? Anyway does anyone know the name of this movie?

I think the movie you're on about is called 'The Biggest fan', I spent ages googling this, hope it helps.

OMG thanks, that's it. It's sooo cheesy but kind of cute =P
