If you’ve spent more than five minutes scrolling through TikTok in the last few years, you’ve probably seen a woman holding a tiny microphone, dispensing dating advice like a modern-day Carrie Bradshaw with a better skincare routine. That’s Christina Najjar, better known as Tinx. But while she’s famous for her "Box Theory" and "Rich Mom" starter packs, there is one question that seems to follow her every comment section: how old is Tinx?
It’s a weirdly persistent thing. Usually, with influencers, people care about their outfits or their drama. With Tinx, people are weirdly fixated on the numbers.
Honestly, I think it’s because she fills this specific niche of "TikTok’s Big Sister." She isn't a Gen Z teenager doing dance trends in her bedroom. She’s someone who has actually lived through her twenties, survived them, and is now looking back to tell us how to do it better.
The Real Numbers: How Old Is Tinx Right Now?
Let’s get the facts out of the way before we get into the "why" of it all. Tinx was born on September 19, 1990. As of January 2026, that makes her 35 years old.
She was born in Washington, D.C., but she grew up in London, which explains that "posh-adjacent" accent that confuses everyone. She eventually moved back to the States for college at Stanford. If you’re doing the math, she graduated in 2012.
It’s actually kinda refreshing to see a creator who didn't find "fame" until her late twenties. Tinx didn't blow up on TikTok until 2020, when the world was shut down and everyone was bored. At that point, she was 29 turning 30. That’s basically a lifetime in "influencer years," where many stars are retired by 25.
Why Everyone Is So Curious About Her Age
So, why do we care?
For one, Tinx leans into the "Big Sister" persona. She’s the one telling you that your crush isn't texting you back because he’s just not that into you, not because he’s "busy." That kind of advice requires some level of life experience. If a 19-year-old said it, you’d roll your eyes. When a woman in her mid-thirties says it, it feels like gospel.
There’s also the "Millennial vs. Gen Z" bridge she walks. She has the work ethic and pop culture references of a Millennial—think The O.C. and early 2000s tabloids—but she speaks the language of TikTok fluently.
The Controversy Factor
You can’t really talk about her age and public perception without mentioning the "Twitter-gate" situation from a few years ago. In 2022, some old tweets of hers from 2012 to 2020 resurfaced. They weren't great. They were fat-phobic and leaned into some mean-girl tropes.
A lot of the backlash wasn't just about what she said, but when she said it. People pointed out that she wasn't a "dumb teenager" when she wrote some of those things; she was in her mid-to-late twenties. That’s where the how old is Tinx question took a bit of a dark turn for a while. People used her age as a yardstick for how much accountability she should have.
She eventually apologized, basically saying she was a different, unhappier person back then. Whether or not you buy that is up to you, but it definitely added a layer of scrutiny to her birthday.

A Career That Didn't Start at 18
Most people think influencers just wake up and are famous. Tinx’s timeline is actually pretty relatable for anyone who felt lost in their twenties.
- Age 19-22: Studying English at Stanford.
- Age 23-25: Working in retail management at Gap Inc. (She’s been very open about the fact that she was actually "bad at her job" there).
- Age 26-28: Attending Parsons for a master's in fashion journalism and freelance writing.
- Age 29: Starts TikTok.
Think about that. She was nearly 30 before the "Tinx" brand even existed.
In a world where we feel like we have to have everything figured out by 22, her story is actually a huge relief. She’s the poster child for the "late bloomer" (though 29 is hardly late, it just feels like it in the digital age).
Life at 35: The New Era of Tinx
Fast forward to today. Tinx isn't just a girl with a phone anymore. She’s a brand.
She has a SiriusXM show called It's Me, Tinx, a New York Times bestselling book (The Shift), and more brand deals than you can shake a "Chipotle bowl" at. She’s effectively turned being "the older girl who knows things" into a multi-million dollar empire.
What’s interesting is how her content has shifted as she’s gotten older. She’s less about the "blackout brunch" vibes and more about "intentional living," mental health, and high-end lifestyle curation. She’s growing up with her audience. The girls who followed her at 21 in 2020 are now 27 and looking for different advice.
The "Rich Mom" Evolution
One of her most famous bits is the "Rich Mom" skits. She’d wear a puffer vest, hold a green juice, and talk about "dropping the kids at Mandarin immersion."
The irony? She’s becoming the person she used to parody. But she’s in on the joke. She calls it "half satire, half aspirational." At 35, she’s closer to that demographic than ever, and her fans seem to love the transition from "hot mess older sister" to "aspirational cool aunt."
Final Insights on the Tinx Timeline
Knowing how old is Tinx isn't just about satisfying celebrity gossip cravings. It actually provides a lot of context for why her advice resonates. She’s lived through the "spiral-y" years she talks about.
