Time moves fast in the Bieber world. One minute, Justin is the kid with the purple hoodie and the swoopy hair, and the next, he’s a father himself. But while everyone is busy tracking Jack Blues Bieber's milestones, people often forget about the original "Little Bieber." If you’re wondering how old is Jaxon Bieber, the answer usually surprises folks because, honestly, we all still picture him as that tiny kid on the Grammys red carpet.
As of right now, in early 2026, Jaxon Bieber is 16 years old.
He’s not a toddler anymore. He’s not even a "little" kid. He’s a full-blown teenager navigating the weird world of being a global superstar's brother while trying to have a normal life in Canada and Los Angeles. He’ll actually be hitting the big 1-7 later this year.
The Birthday Math You’re Looking For
Jaxon was born on November 20, 2009.
If you do the quick math, that makes him a Scorpio. It also means he’s currently in that sweet spot of teenage life where he’s probably thinking about driving, finishing up high school, and maybe even carving out a career that doesn't just involve being "Justin's brother."
To break it down for the current year:
- January to November 19, 2026: He is 16.
- November 20, 2026: He turns 17.
It’s kind of wild to think that when Jaxon was born, Justin was just beginning his meteoric rise with "One Time" and "Baby." Jaxon has quite literally grown up in the shadow of one of the biggest fame engines in history.
Growing Up "Bieber"
Jeremy Bieber and Erin Wagner (Jaxon’s mom) have done a pretty decent job of keeping him grounded, or at least as grounded as you can be when your brother is worth hundreds of millions of dollars. Jaxon has always been Justin’s "mini-me."
You've probably seen the photos. The matching baggy clothes, the similar blonde hair, the "too cool for school" poses. Justin has always been incredibly protective of Jaxon. In fact, Justin often refers to him as his "best friend" or his "precious little bro."
But 16 is a transitional age. We’re seeing Jaxon move away from just being a prop in Justin’s Instagram feed to being his own person. He’s got his own following—over a million on Instagram—and while his parents still help manage the account (because, let’s be real, the internet is a toxic place for teens), his personality is starting to shine through. He’s into boxing, fashion, and travel.
The Sibling Dynamic in 2026
The Bieber family tree is a bit sprawling, so if you're confused about where Jaxon fits, here’s the reality:
- Justin is the eldest (the megastar).
- Jazmyn is his full sister (from Jeremy and Erin), who is about a year and a half older than Jaxon. She’s 17 now and turns 18 in May.
- Allie Rebelo is his stepsister (Jeremy’s wife Chelsey’s daughter), who is the oldest of the "younger" group at 18.
- Bay Bieber is the youngest sister, born in 2018, making her just 7 years old.
It's a loud, busy house whenever they all get together.

Why Jaxon Still Matters to the Fandom
You might wonder why anyone cares about a 16-year-old’s age. It’s because the "Beliebers" who grew up with Justin feel a maternal or big-sisterly connection to his siblings. Seeing Jaxon grow up feels like watching a timeline of our own lives.
There was a moment at Coachella 2025 that went viral—Justin and Jaxon were hanging out, and people couldn't believe how tall Jaxon had gotten. He’s basically catching up to his dad and brother. At 16, he’s no longer the kid Justin carries on his shoulders. He’s the guy standing next to him in the VIP section.
What’s Next for Jaxon?
At 16, the world is pretty much his oyster. There’s always been talk about whether he’ll go into music like Justin. He’s been seen in studios and around musical equipment since he could walk. However, he seems just as interested in the lifestyle side of things—modeling, fashion, and sports.
Honestly, the kid has a level of "cool" that most 16-year-olds would kill for. Whether he chooses to step into the spotlight or stay behind the scenes, he’s got the ultimate mentor in his corner.
If you're keeping tabs on him, just remember that he's entering those "scary" late-teen years. 17 is just around the corner, and 18 isn't far behind. Pretty soon, we won't be calling him "Little Bieber" anymore.
To keep up with Jaxon's latest milestones, the best bet is usually his Instagram or Jeremy’s frequent family updates. Just don't be shocked when he posts a photo of a car soon—16 is that age, after all.
