Mae Whitman and Robbie Amell's new movie The DUFF hits theaters tomorrow and the two stars celebrated at NYC Planet Hollywood today by donating memorabilia from the film. Robbie donated the football jersey he wore in the movie and Mae gave them her "lucky party shirt" (you'll understand after you see the film!).
