What happens when the princess of pop meets the queen of indie-comedy chaos? You get a friendship that feels like a fever dream and a marketing masterclass rolled into one. If you’ve been anywhere near TikTok or Twitter lately, you’ve seen them. Rachel Sennott and Sabrina Carpenter are basically the blueprint for the "It Girl" crossover.
One is a scream queen who got her start doing stand-up on Twitter and starring in claustrophobic indie hits like Shiva Baby. The other is a former Disney star who just spent the last year colonizing the Billboard charts with earworms like "Espresso." On paper, they’re from different worlds. In reality, they are the codependent, chaotic duo we didn't know we needed.
Honestly, their connection isn't just about grabbing drinks at the Chateau Marmont—though they definitely do that. It’s about a shared sensibility. They both traffic in a very specific kind of irony. Sabrina’s lyrics are self-aware and cheeky; Rachel’s writing is cringe-inducing and raw. When they finally appeared on stage together, the internet didn't just notice—it obsessed.
The "Juno" Arrest That Changed Everything
If you want to pinpoint the exact moment this friendship went from "cool rumor" to "cultural canon," look back at November 15, 2024. Sabrina was performing her Short n' Sweet Tour at the Crypto.com Arena in Los Angeles. During her performance of "Juno," she does this bit where she "arrests" a celebrity in the audience for being too hot.
Most people expected a fellow pop star. Instead, out comes Rachel Sennott.
Rachel didn't just stand there. She leaned into the bit with the kind of comedic timing that made her a star in Bottoms. Sabrina put her in fluffy pink handcuffs. The crowd lost it. That single moment solidified the Rachel Sennott and Sabrina Carpenter link for the masses. It wasn't just a cameo; it was a vibe check. It told the world that Sabrina isn't just a pop star—she’s part of the "cool girl" comedy inner circle.

Why the "It Girl" Crossover Matters
Pop culture used to be siloed. You were either a serious actor or a pop singer. Now? The lines are gone. Rachel and Sabrina represent a new era where fame is fluid.
- Ayo Edebiri is often seen with them, forming a sort of "Power Trio" of young Hollywood.
- They share a specific aesthetic: vintage-inspired, slightly messy, and very high-fashion.
- They both utilize "internet speak" in a way that feels authentic rather than forced.
HBO’s "I Love LA" and the Shared Creative Circle
By late 2025, the professional ties between the two became even clearer. Rachel Sennott finally launched her highly anticipated HBO comedy, I Love LA. The show, which Rachel wrote, stars in, and executive produces, is a semi-autobiographical look at a codependent friend group in Hollywood.
While Sabrina isn't a series regular—that honor goes to Josh Hutcherson and Jordan Firstman—her fingerprints are all over the scene. Lorene Scafaria, who directed the pilot for Rachel’s show, also signed on to direct Sabrina’s Alice in Wonderland musical project for Universal.
It’s a small world.
In I Love LA, Rachel explores the exact kind of high-stakes, high-anxiety friendship that fans speculate she has with people like Sabrina. They are navigating fame at the same time, just in different lanes. When Sabrina was spotted at the W Magazine Best Performances Party in January 2025 sitting next to Rachel and Ayo Edebiri, it wasn't just a photo op. It was a glimpse into the new Hollywood establishment.

What People Get Wrong About the "Industry Plant" Narrative
Look, whenever two people this successful become friends, the "industry plant" or "PR friendship" accusations start flying. People love to think everything is a calculated move by a manager in a suit.
But with Rachel Sennott and Sabrina Carpenter, the math doesn't quite add up for a fake friendship. Rachel’s brand is built on being unfiltered. She’s the girl who posted through her breakups on Twitter for years. Sabrina, while more polished, has a wicked sense of humor that matches Rachel’s beat for beat.
The reality? They probably just find each other funny.
The "Short n' Sweet" era of Sabrina's career has been defined by her ability to not take herself too seriously. Who better to help you lean into that than the woman who made a movie about a girl fight club? Their friendship feels like a mutual admiration society. Rachel gets to inhabit the pop-glamour world, and Sabrina gets "indie-cred" by association.
Making the Most of the "It Girl" Energy
If you're a fan trying to keep up, you've got to look beyond the Instagram stories. The real magic of the Rachel Sennott and Sabrina Carpenter connection is in how they support each other's work.

Watch for these specific cues:
- Wardrobe Swaps: Notice how their stylists (like Molly Dickson) often pull from the same 90s-inspired archives.
- Music Video Cameos: Keep your eyes peeled for Rachel in future Sabrina visuals. The "Please Please Please" video showed Sabrina's love for cinematic, actor-heavy storytelling.
- Writing Credits: Don't be surprised if Rachel ends up with a "consultant" or "thank you" credit on Sabrina’s next project, or if Sabrina provides music for I Love LA.
Actionable Insights for Fans and Creators
If you're looking to capture even a fraction of this "It Girl" energy in your own content or career, take a page from their book.
- Collaborate across niches. If you’re a writer, talk to a musician. If you’re a gamer, talk to a chef. The most interesting things happen at the intersection of different worlds.
- Lean into the "unpolished" look. Both women have mastered the art of the "high-low" aesthetic. It makes them feel reachable, even when they’re at the Met Gala.
- Prioritize humor. In 2026, being "cool" is secondary to being funny. If you can make people laugh at your own expense, you win.
Rachel Sennott and Sabrina Carpenter aren't just a flash in the pan. They represent a shift in how celebrity works. It’s less about mystery and more about the "friend group" dynamic. Whether they're fake-arresting each other on stage or supporting each other at HBO premieres, they are proving that in the modern entertainment landscape, the only thing better than being a star is being a star with a really cool best friend.
Keep an eye on the credits for the second season of I Love LA. The rumors of a Sabrina guest spot aren't going away, and given their history, it’s probably only a matter of time before the "Espresso" singer makes her way into Rachel’s chaotic TV universe.
