does anyone know where i can get mia's diary from the movie ?

You could try ebay.com, or yahoo shopping. You may also want to try a speciality store that can tell you about the kind of diary you are looking for. A diary with a locket as the key is probably hard to find. Personally, I've never seen one, but that doesn't mean you can't find one if you look hard enough. The diary in the movie The Princess Diaries looks like a leather cover. Good luck with your search!

mia's diary,hmm u mean princess diaries right?

Which movie are you talking about... is it called "mia's diary"??
