Katherine Heigl & Shonda Rhimes
Former Grey's Anatomy star Katherine Heigl started a feud with the series creator when she removed her name from the Emmy Wards consideration. Heigl felt that she wasn't "given the material to warrant a nomination," and was angry that her character's importance in the show was significantly cut. Eventually, Heigl left the show, and Rhimes revealed that the snub stung, but she believes people when they show their true colors.
