Constance Erica "Connie" Thompson, also known as Creepy Connie, is a fourteen-year-old girl who has an obsessive, psychotic crush on Luke Ross. In Creepy Connie Comes a Callin', her debut episode, she is his math tutor to fool Jessie so she has no clue how crazy/creepy Connie can be. Connie wrongly accuses Jessie and Luke of being a couple. Soon Jessie finds out who she really is, and when Connie breaks into the Ross house dressed as a dementor from Harry Potter, everyone realizes that she's a psycho, except for Luke who knew it all along. In Creepy Connie's Curtain Call she tried out for Jessie's play and got cast as a tumbleweed. Because the female lead got to kiss Luke, she got rid of all the other female leads so she could have it and kiss Luke. In the end she reveals the reason she obsesses over Luke is because she doesn't think any guy will be into her. Then Ravi says he'd be happy to have any girl (including Connie) as a girlfriend, and they hit it off. She is back being creepy along with Mackenzie, an actress she hired to pretend to be her former boarding school roommate and to make Luke think that Mackenzie's another girl who becomes obsessed with him in Creepy Connie 3: The Creepening.
She is portrayed by Sierra McCormick.
