Lilly Moscovitz is the best friend of Mia Thermopolis, Princess of Genovia. Sometimes Mia thinks of her pug-faced best friend as a know-it-all, someone with a lot of knowledge that Mia doesn't have a clue to. Lilly is the sister of Michael, the boy with the nice chest that Mia loves. Lilly runs her own cable television show, that sadly, only reaches a few people.
