Emily Ratajkowski, aka the most pouty-lipped of the pouty-lipped half-naked ladies in Robin Thicke's "Blurred Lines" video, has been cast as the mistress, Andie, in the movie adaptation of Gillian Flynn's novel Gone Girl. Model/actress! As you may recall if you read the book, Andie is Nick's student who writes a story about a stripper that "reads like a Penthouse Forum piece," and then possibly seductively eats an apple, which kind of kicks things off between them. We don't know much about Ratajkowski's acting chops, but since Andie's identifying qualities are that she is young and a little ditzy, she should be fine.
