Ever walked past a TV and thought, "Wait, is Katy Perry in New Girl?" only to realize it’s actually Zooey Deschanel? You aren't alone. Honestly, it’s one of the most persistent glitches in the Hollywood matrix. For over a decade, fans have been squinting at their screens trying to figure out which raven-haired, blue-eyed star is currently staring back at them.
But here's the thing: it isn't just one person. There’s a whole "type" that seems to share the exact same genetic blueprint. It’s kinda wild when you look at the photos side-by-side.
People always talk about the main few, but the list of celebrities that look like Katy Perry is actually much deeper—and weirder—than most realize. From British soap stars to Oscar-winning actresses, the resemblance across this group is uncanny.
The Zooey Deschanel Connection: More Than Just Bangs
We have to start with the obvious one. Zooey Deschanel.
For years, these two were basically considered the same person by anyone who wasn't a die-hard fan. They share the pale skin, the wide-set blue eyes, and that specific "indie-girl" aesthetic that dominated the mid-2000s. It got so bad that Katy actually used it to her advantage.
In a 2020 Instagram Live with Zooey, Katy admitted that when she first moved to Los Angeles around 17 years old, she was a total nobody. Zooey, meanwhile, was already a massive star. Katy confessed that she would pretend to be Zooey just to get into exclusive clubs.
"I wanted to get into the club, but I had no money, I had no clout," Katy said. She’d put on the persona, and bouncers—who apparently didn't look too closely—would let her right in.

Zooey’s reaction? She knew. People would come up to her and say they’d seen her out "partying" and being a "wild child" at the club. Zooey, who describes herself as a total "goody-two-shoes," was always confused until she finally met Katy and realized why everyone was so certain they’d seen her out at 3:00 AM.
The two finally leaned into the joke for Katy's "Not the End of the World" music video, where aliens accidentally abduct Zooey because they think she’s Katy. It’s probably the most meta moment in celebrity doppelgänger history.
The British Double: Siwan Morris
If you grew up watching the UK show Skins, you probably did a double-take during the first two seasons. Siwan Morris, who played Angie, bears a shocking resemblance to Katy Perry.
It’s the bone structure. They both have that slightly pointed chin and high cheekbones that make them look like they could be sisters. While Katy was rising to fame with "I Kissed a Girl," Siwan was already a staple on British television.
It isn't just a fan theory, either. UK tabloids have been pointing out the "Siwan Morris is Katy Perry" thing for years. When they both wear their hair dark with heavy fringe, the likeness is almost 1:1.
Emily Blunt and the "Blue-Eyed Brunette" Template
Emily Blunt is another name that frequently pops up in this conversation. While she’s often seen with lighter hair or different styling now, during her early Devil Wears Prada era, the comparison was constant.

What links Emily to the "Katy Perry look" is the intensity of the eyes. There’s a specific way the blue eyes pop against dark hair that creates a visual signature.
Experts in facial recognition often point out that humans are wired to look for specific high-contrast features. When you have:
- Dark brown or black hair
- Highly pigmented blue eyes
- Fair, porcelain-toned skin
Your brain almost automatically groups these people together. This is why fans often include Mia Kirshner (from The L Word) and Katie Featherston (from Paranormal Activity) in this group. They all fit the same high-contrast archetype.
Why Do We Get Them Confused?
Biologically, it's about "feature-based processing." Our brains aren't always looking at the micro-details like nose shape or earlobes. Instead, we look at the "holistic" image.
In the case of celebrities that look like Katy Perry, the "holistic" image is dominated by the eyes and the hair. Because Katy has famously changed her hair color dozens of times—going from neon pink to "slime green" to platinum blonde—it actually makes it easier to confuse her with others. When she’s in her natural brunette state, she blends back into that group of actresses who have occupied that look for decades.
The Next Generation: Francesca Capaldi
Resemblance isn't just limited to people the same age. As Katy has matured in the spotlight, fans have noticed younger stars who look like they could be her mini-me.

Francesca Capaldi, known for her roles on Disney Channel, has been dubbed "Young Katy" by segments of the internet. While she’s mostly known for her red curls, when her hair is straightened or styled differently, the facial features—specifically the rounder face shape and large eyes—are incredibly similar to Katy's earlier look.
The Nuance of the "Lookalike" Label
Honestly, none of these women are identical twins. If you put them in a room together without makeup, you’d probably tell them apart in five seconds.
The "lookalike" phenomenon is largely driven by styling. The mid-2000s "Pin-up" and "Zooey Deschanel" aesthetic became so popular that many women in Hollywood were styled to look exactly like each other.
The heavy bangs (fringe) are the biggest culprit. Bangs act like a frame for the face, hiding the forehead and drawing all the attention to the eyes. When you take the bangs away, the "lookalike" effect usually drops by about 50%.
Actionable Insights for Fans and Creators
If you’re a fan trying to tell them apart or a creator looking to understand why these comparisons go viral, here are a few things to keep in mind:
- Check the voice: While they look similar, their vocal registers are completely different. Katy has a deep, husky singing voice; Zooey has a very distinct, quirky "indie" alto.
- Look at the height: Katy Perry is about 5'7", while Zooey Deschanel is closer to 5'5". Emily Blunt is also around 5'7", making her a closer physical match in terms of stature.
- Style cues: Katy’s style is "Camp"—it’s loud, colorful, and often involves food-themed outfits. Zooey’s style is "Twee"—think vintage dresses, cardigans, and 60s-inspired flats.
- The "Bangs" Test: If you're looking at a photo and you aren't sure, look at the forehead. Katy often shows her forehead or wears high ponytails; Zooey is almost never seen without her signature bangs.
The world of celebrities that look like Katy Perry is a testament to how much "the look" of an era defines our perception of people. Whether it’s a deliberate career move—like Katy's early club-hopping days—or just a coincidence of DNA, these doppelgängers continue to fascinate us because they remind us that even the most "unique" stars have a double somewhere in the world.
To really see the difference, try looking at photos of them from 2024 or 2025. As they've aged and moved away from the 2010-era styling, their individual features have become much more distinct.
