Now, we've caught wind on the fact that singer Pia Mia has been cast as well, making her big-screen debut!
According to Collider, Pia is in talks to play the role of Tristan. In the book, the role was male — but Anna confirmed that they will be gender swapping the role for the movie.
While Pia hasn't herself confirmed the news, we'd love to see her on the big screen.
