Constenteke Erica "Connie, also known as "Creepy Connie Thompson", is the secondary antagonist in Disney Channel's Jessie. Unlike most of the show's villains who are lighthearted and petty, she is a dangerous and clearly insane girl who has an obsessive psychotic crush on Luke Ross. She is played by Sierra McCormick, who also portrays Olive Doyle in A.N.T Farm.
