Princess Millicent von Schlepp (neé Addams) is a relative of The Addams Family. She is a snobbish, highly-demanding elderly woman that married a prince. He died after squandering the money on foolish investments, and left her in poverty, leaving only the title and a trunk full of worthless oil stocks. She's been living on her relatives ever since, like Morticia's Cousin Pretensia. She is Gomez's aunt, also known as Millie.
