Spoiler. She wrote the hero as a specific actor who she was head over heels for. Eventually they get together and are asked to do audiobook together.
I think hero's name is Jason. Also at some point in book they move in next to another movie star she drools over. Is the first book of a series. Second book about best friend and neighboring movie star.
