Caroline Rhea and her longtime boyfriend, Costaki Economopoulos, welcomed their first child on Monday in New York, her rep tells People. Ava Rhea Economopoulos came into the world weighing 8 lb., 15 oz. and measuring 22½. "We wanted the shortest first name possible, since her last name is the alphabet," says the new mom, 44. "It was either that or Emmy, because I've always wanted an Emmy."
