He’s not exactly a baby anymore. Actually, far from it. If you still picture the tiny kid in thick glasses sitting on Chris Pratt’s lap during a Hollywood Star ceremony, you’re about a decade behind.
Jack Pratt today is officially a teenager.
He hit the big 13 in August 2025, a milestone that sent his dad into a bit of a social media tailspin. Chris posted a gallery of photos that basically tracked a decade of growth in a few swipes. We saw Jack feeding baby cows, wearing matching Dodgers jerseys, and even trying his hand at welding. It was a rare, intimate look at a kid who has spent most of his life shielded from the more aggressive parts of the paparazzi lens.
Honestly, it's wild to think about how much has changed for this family. When Jack was born nine weeks premature back in 2012, things looked pretty scary. He weighed only 3 pounds and 12 ounces. His parents, Anna Faris and Chris Pratt, were told he might face significant developmental challenges.
Fast forward to 2026, and he’s the "solid anchor" of a massive, blended Hollywood family.
The Reality of Jack Pratt Today
The kid is a big brother now—four times over. While he's the only child of Anna and Chris, he’s become the veteran sibling in the Pratt-Schwarzenegger household.
Chris and Katherine Schwarzenegger have been busy. They recently celebrated the first birthday of their youngest, Ford Fitzgerald, in November 2025. This means Jack is navigating the world of middle school while also being the cool older brother to Lyla (5), Eloise (3), and baby Ford.

Pratt told Entertainment Tonight that Jack is "so sweet" with the younger kids. There's a big age gap there, but apparently, the little ones absolutely worship him. When he's gone, they miss him. That’s a pretty high endorsement for a thirteen-year-old boy.
What’s Life Actually Like for Him?
He’s living that "normal-ish" celebrity kid life. In early 2026, Chris Pratt made an appearance on The Graham Norton Show and dropped a hilarious detail about their Christmas.
Apparently, Jack’s grandfather-in-law, Arnold Schwarzenegger, is a bit of an intense gift-giver. He gave the family a 6-foot-by-8-foot oil painting of all the kids with Arnold dressed as Santa. Imagine being 13 and having a massive, life-sized portrait of yourself and your siblings being watched over by the Terminator in a red suit.
That’s the kind of "beautiful chaos" Chris talks about.
Jack also spends a lot of time on sets. He was recently in London with his dad while Chris was promoting his new sci-fi thriller Mercy. He’s not just a bystander, either. During the filming of The Tomorrow War, his dad let him get into the harness and "fly" around, shooting imaginary lasers.
But it’s not all movie sets and giant paintings.

Anna Faris has been very open about their co-parenting dynamic. She mentioned on Today that Jack is going through all the standard teenage stuff. You know, the "mom, I have an armpit hair" phase. She calls him her "down-to-earth" boy.
The Public’s Obsession with the "Healthy" Comment
You can't really talk about Jack Pratt today without mentioning the 2021 Instagram drama. It’s the elephant in the room.
Back then, Chris Pratt posted a tribute to Katherine Schwarzenegger, thanking her for a "gorgeous healthy daughter." The internet absolutely lost its mind. People assumed it was a direct dig at Anna Faris because Jack had dealt with health issues following his premature birth.
Pratt later told Men's Health that the backlash made him cry. He was devastated that his words were twisted in a way that might one day hurt Jack.
"My son's gonna read that one day," he said.
In reality, the relationship between the four parents—Chris, Katherine, Anna, and Anna’s husband Michael Barrett—is reportedly great. They live near each other and prioritize Jack's stability above everything else. Anna even joked about the "fantasy idea" of them all vacationing together.
Health and Development: Where Things Stand
Despite the early warnings from doctors about "severe brain bleeding" and potential disabilities, Jack has thrived.

He’s had five surgeries over the years and spent plenty of time in physical therapy. He still wears glasses, which has become a bit of his signature look, but by all accounts, he is a happy, active teenager. He catches massive fish with his dad, goes to Dodgers games, and hangs out with friends at private screenings of The Super Mario Bros. Movie.
He’s basically living a life that balances high-profile events with very low-profile personal time.
What's Next for Jack?
As he enters his mid-teens, the question is always whether he'll catch the acting bug. Both of his parents are comedic geniuses. His step-grandfather is a global icon.
For now, he seems content being a "solid anchor."
If you're following the journey of the Pratt family, here are a few things to keep in mind regarding Jack’s presence in the media:
- Privacy is Priority: Don't expect a public Instagram from him anytime soon. His parents have been very careful about when and how they show his face.
- The Blended Dynamic: Watch for more updates on how he interacts with his younger siblings; he's clearly the "leader" of the pack.
- Academic Life: He’s at that age where high school is looming. Most of his "news" will likely center around sports and family milestones rather than career moves.
Jack Pratt’s story is a pretty incredible one of resilience. From a 3-pound preemie to a 13-year-old welding enthusiast and big brother, he’s carving out a very different path than the one doctors predicted back in 2012.
