You’ve probably seen her face everywhere lately. Whether she’s causing chaos in the wasteland of Borderlands or giving Margot Robbie a reality check in Barbie, Ariana Greenblatt is basically the "It Girl" of the mid-2020s. But there is a weird thing that happens when a child actor suddenly becomes a massive movie star. People lose track of time. They remember her as the tiny girl from Disney, then they see her on a red carpet looking like a grown adult, and the first question is always: wait, how old is Ariana Greenblatt actually?
Honestly, the timeline is a bit of a trip.
The Short Answer (No Fluff)
Let’s get the math out of the way first so you can stop guessing. Ariana Greenblatt was born on August 27, 2007. Since we are currently in early 2026, she is 18 years old.
She’s officially an adult. It feels weird, right? Most of us still have that mental image of her as Daphne Diaz in Stuck in the Middle, where she was literally seven or eight years old. But time doesn't stop for Disney stars. She spent her entire childhood on camera, and now she's navigating that tricky transition into "serious" adult roles while most people her age are just trying to figure out their college majors.
The "Young Gamora" Confusion
One of the reasons people get so confused about her age is her role in the Marvel Cinematic Universe. Back in 2018, she played Young Gamora in Avengers: Infinity War.
Think about that for a second.
When that movie came out, she was only 10. But because that film is such a massive cultural touchstone, people keep rewatching it. Every time someone sees her sitting there with Thanos, they’re seeing a version of Ariana from nearly a decade ago. It creates this weird "Peter Pan" effect where the audience expects her to stay that age forever.

Then, she shows up in 2023's Barbie as Sasha, a cynical teenager, and the collective internet has a meltdown because she "grew up so fast." She didn't. She just grew up normally; we just weren't paying attention.
Why Her Age Actually Matters in 2026
In the industry, 18 is the magic number.
Before now, Ariana was subject to strict child labor laws. On sets like 65 (with Adam Driver) or Ahsoka, she could only work a certain number of hours before she had to go to "school" in a trailer. Now that she’s 18, those restrictions are basically gone. She can pull the 14-hour days that big-budget action movies usually require.
This is a huge turning point.
We’re already seeing the results of this shift in her 2025 and 2026 projects. She’s moved from "the kid in the movie" to a lead actress who can carry a franchise. Look at her role in Now You See Me: Now You Don’t (the third installment) or the thriller Hot Ted. She’s playing characters with more edge, more complexity, and—let’s be real—more adult problems.
A Quick Timeline of the "Grow Up" Years:
- 2016: Hits the scene in Stuck in the Middle (Age 8-9).
- 2018: Becomes an icon as Young Gamora (Age 10).
- 2021: Films Borderlands (She was actually only 13 during filming, though it came out much later).
- 2023: Breaks the internet in Barbie (Age 15 during filming, 16 at release).
- 2025: Transitions to adult roles in Fear Street: Prom Queen (Age 17-18).
- Today (2026): Fully established as an 18-year-old leading lady.
The "Borderlands" Delay Factor
If you saw Borderlands recently and thought she looked younger than she does in her recent Instagram posts, you aren't crazy.
That movie sat on the shelf for a long time. It was filmed way back in early 2021. At that time, Ariana was barely a teenager—only 13 years old. By the time the world actually saw her as Tiny Tina, she was already pushing 17.
That’s a massive gap in "teenager years." A 13-year-old and a 17-year-old are practically different species. This is one of the pitfalls of being a young actor; sometimes your work is released so late that it feels like a time capsule.
Navigating Fame at 18
It’s not just about the movies. Ariana has become a massive style icon. If you check her social media or see her at Fashion Week, it’s clear she’s leaning into a more mature, high-fashion aesthetic.
She’s mentioned in interviews how hard it is to "live a double life." On one hand, she’s doing press tours with Cate Blanchett and Ryan Gosling. On the other hand, she was still dealing with high school tutors and "normal" teen angst until very recently.
She has a Puerto Rican and Jewish background, which she’s been very vocal about, and that groundedness seems to be keeping her from the typical "child star meltdown" we’ve seen so many times before. Plus, her dad, Shon Greenblatt, was an actor too. Having a family that actually understands the business—the good and the bad—is probably the only reason she’s as sane as she is at 18.
What's Next for Ariana?
Now that she’s officially 18, the "kid" label is officially gone.
The industry is watching her closely. She’s following in the footsteps of people like Jenna Ortega (who she actually worked with on Stuck in the Middle) and Zendaya. These are actresses who successfully navigated the "Disney-to-Diva" pipeline without losing their minds.
Expect to see her in more "Prestige TV" and indie films. She has the range—we’ve seen her do comedy, sci-fi, and heavy drama. Now that she can work adult hours and take on more mature scripts, the ceiling is pretty much non-existent.

Actionable Takeaways for Fans and Follower:
- Watch the early stuff: If you only know her from Barbie, go back and watch Love and Monsters. She’s incredible in it, and it shows her range before the massive fame hit.
- Check the release dates: If she looks "young" in a movie, check when it was filmed. The 2021-2024 period had a lot of production delays that messed with our perception of her age.
- Follow the fashion: If you’re into style, her 2026 red carpet run is expected to be a major shift as she fully embraces her adult image.
- Look for "Now You See Me: Now You Don’t": This is her big test as a member of an ensemble adult cast.
Ariana Greenblatt isn't a kid anymore. She's a veteran actor with over a decade of experience who just happens to have finally reached legal adulthood. Keep that in mind next time you see her on screen—you’re watching someone who has already put in 10,000 hours before most people even get their first job.
