Jessica Simpson got into the Halloween spirit to announce her pregnancy yesterday! "It's true! I am going to be a mummy!" she wrote on her website, along with a photo of her costume—a sequined mummy outfit! This is the first child for Simpson and her fiancé, former pro football player Eric Johnson. Congratulations to the mummy-to-be!
Plus, see sister Ashlee with son Bronx, and more celebrity mom style in the gallery!
