Katherine Kelly is the descendant of Elsa Olden. Her father is unknown. She has lived in Auradon with her mother for her whole life. Katherine is known as being the most bubbly and innocent girl.. all that will change when she meets Carlos..🌙🖤

Katherine Smith (Katie) is played by Ariana grande because I feel like Ariana had good features that would go good with the story line. Katie had known Billy for years. He always teased her and embarrassed and bullied her at school. But since Katies brother Josh is best friends with Billy Katie just has to constantly put up with Billy. But maybe she might feel something a little more for Billy than she actually knows..🖤
