From Wikipedia, the free encyclopedia. Julie Ann Brown (born August 31, 1958) is an American actress, comedienne, novelty singer-songwriter and screenwriter. Brown is perhaps best known for her work in the 1980s, where she often played a quintessential valley girl character. Much of her comedy has revolved around the mocking of famous people (with a strong and frequently revisited focus on Madonna).
