The new film "The DUFF" stars Mae Whitman as a high school student named Bianca. She's a somewhat ordinary looking girl whose two best friends are good-looking and popular. All is well until she's told one day that she's a "DUFF," a "designated ugly fat friend."
The film is based on the debut novel from author Kody Keplinger, who wrote the book when she was just 17.
Keplinger joined Take Two to talk about how she got the idea for the book, why we're all DUFFs in some way, and what it's been like to see her book translated into a film.
