Jamie Lee Curtis (born November 22, 1958) is a American film actor and author of children's books. Although she was initially known as a "scream queen" because of her starring roles in many horror films early in her career such as Halloween, The Fog, Prom Night and Terror Train, Curtis has since compiled a body of work that covers many genres. Her 1998 book, Today I Feel Silly, and Other Moods That Make My Day, made the best-seller list in The New York Times. She is married to actor Christopher Guest (Lord Haden-Guest) and, as the wife of a lord, is titled Lady Haden-Guest, but she chooses not to use the title when in the United States. She is currently the spokeswoman for Activia. She is also a blogger for The Huffington Post online newspaper.
