You remember the glasses. The frantic, wide-eyed stare. The way she’d pop up out of nowhere just to declare her undying, slightly terrifying love for Luke Ross. If you grew up watching the Disney Channel in the early 2010s, "Creepy Connie" was the recurring character you both loved to laugh at and low-key feared would show up in your own basement. But honestly, who plays Creepy Connie in Jessie?
The actress behind the madness is Sierra McCormick.
While she’s iconic for that specific role, her journey from a child star on one of the biggest sitcoms of the era to a critically acclaimed indie horror darling is one of the most interesting pivots in Hollywood right now. Most people see her and think "stalker girl," but there’s a whole lot more to her story than just a pair of prop spectacles and a script full of Luke-obsessed monologues.
The Identity of Creepy Connie: Sierra McCormick's Breakthrough
Sierra McCormick took on the role of Connie Thompson—affectionately and accurately dubbed "Creepy Connie"—starting in 2011. She wasn't just some random guest star; she brought a specific, manic energy that made Connie feel like a genuine threat to poor Luke Ross, played by the late Cameron Boyce.
Connie first appeared in the episode "Creepy Connie Comes a Callin’," where she was originally hired as a tutor. It didn't take long for the math problems to turn into shrine-building. What made Sierra's performance so effective was her ability to flip between a sweet, innocent girl and a dead-eyed obsessed fan in about 0.5 seconds.

She wasn't just playing a trope. She was leaning into the absurdity.
Why Connie Still Matters to Fans
The character was so popular that she returned for multiple episodes, including "Creepy Connie’s Curtain Call" and "Creepy Connie 3: The Creepening." Even when Sierra McCormick was busy starring in her own lead role on the Disney show A.N.T. Farm, she still made time to come back to Jessie. That says a lot about her relationship with the cast and her willingness to play a character that was, frankly, kind of weird.
Actually, the behind-the-scenes vibes were apparently the total opposite of the on-screen tension. Sierra and Cameron Boyce were actually friends in real life, which probably made those awkward staring matches a lot easier to film without breaking into laughter every two minutes.
Where is Sierra McCormick Now?
If you haven't kept up with Disney alumni, you might think Sierra just disappeared after the channel stopped airing A.N.T. Farm in 2014. That couldn't be further from the truth. In fact, she’s become a bit of a legend in the indie film circuit.

She made a massive splash in 2019 with a sci-fi movie called The Vast of Night. If you haven't seen it, go watch it on Amazon Prime. She plays Fay Crocker, a 1950s switchboard operator who hears a mysterious frequency. It’s a complete 180 from Creepy Connie. Her performance is grounded, technical, and incredibly mature. She basically carried long, unbroken takes where she's just operating a switchboard and talking on a headset, and it’s genuinely gripping.
Recent Projects and Horror Roots
Sierra seems to have a bit of a thing for the macabre. Maybe playing Connie gave her a taste for the dark side? She starred in the 2021 horror film We Need to Do Something, which is a claustrophobic nightmare set entirely in a bathroom during a storm. She also appeared in the first season of American Horror Stories (the spin-off of American Horror Story), playing Scarlett Winslow in a multi-episode arc.
As of 2025 and 2026, she's continued to lean into these "edge-of-your-seat" roles. Her latest project, Killing Mary Sue, shows she hasn't lost that spark for playing characters with a bit of a bite. She's also popped up in thrillers like The Last Stop in Yuma County.
What Most People Get Wrong About the Cast
There is a common misconception that Jessie stars either stay in the Disney bubble or flame out. Sierra McCormick is the living proof that you can take a "joke" character and use it as a springboard for a serious, long-term career.

Some fans also confuse Connie with other guest stars from that era. For example, G Hannelius (of Dog with a Blog fame) appeared in one of the Connie episodes as a rival named Mackenzie, but she wasn't the "original" Creepy Connie. That title belongs solely to Sierra.
The Evolution of the "Disney Star"
The transition from Disney kid to adult actor is notoriously hard. You’ve got to shed the "bright and shiny" image without becoming a tabloid headline. Sierra did this by choosing scripts that were artistically challenging rather than just going for the biggest paycheck. She chose indie darlings over safe network procedurals.
- 2011-2014: The Disney Era (A.N.T. Farm, Jessie)
- 2015-2018: The Transition (Some Kind of Hate, Pretty Little Stalker)
- 2019-Present: The Indie Powerhouse (The Vast of Night, American Horror Stories)
Actionable Insights: How to Follow Her Career
If you’re a fan of the show and want to see what "Connie" is up to these days, don't just wait for a Disney reboot that probably isn't happening.
- Check out the "Indie" Side: Watch The Vast of Night. It’s widely considered one of the best sci-fi films of the last decade, and it’s where Sierra really proved her range.
- Follow the Horror Scene: If you like darker content, keep an eye on her filmography on platforms like Tubi or Shudder. She’s become a staple in the "elevated horror" genre.
- Social Media Presence: She’s active on Instagram and Twitter (X), often sharing behind-the-scenes looks at her smaller film sets which feel a lot more personal than the big studio accounts.
Sierra McCormick managed to take a character defined by being "creepy" and turned her talent into a career that is genuinely impressive. She's no longer just the girl with the Luke Ross shrine; she's a formidable actress who knows exactly how to command a screen, whether she’s being funny, scary, or just plain brilliant.
To dive deeper into the Jessie universe, you can find the original "Creepy Connie" episodes streaming on Disney+. It’s worth a rewatch just to see how much work Sierra was actually putting into those facial expressions—it’s physical comedy at its best. Beyond that, keep an eye on independent film festival circuits, as that's where her most exciting work is debuting these days.
