Not yet, but it could well get turned into a movie, it says this on the gallagher girls website: What do THE CHRONICLES OF NARNIA, CHARLOTTE'S WEB, BRIDGE TO TERABITHIA, and I'D TELL YOU I LOVE YOU, BUT THEN I'D HAVE TO KILL YOU have in common? They are all movie projects at Walden Media! Walden Media, the book-to-film specialists, have purchased the Love You/Kill You option from Walt Disney. Producers have been assigned and a screenplay is in the works, which is very exciting for the Gallagher Girl series!
