Who is Paul Rudd’s Son? What We Know About Jack Sullivan Rudd

It is a weird thing, seeing double. You’re scrolling through Twitter or watching a post-game Super Bowl interview, and suddenly there’s Paul Rudd—the man who apparently found the Fountain of Youth sometime in the late ’90s—standing next to a teenager who looks and, more importantly, sounds exactly like him.

That teenager is Jack Sullivan Rudd, and he has spent the last few years accidentally becoming an internet sensation just by standing next to his dad.

People are obsessed. It isn't just the face, although the resemblance is definitely there. It’s the vibe. The energy. The way he talks about football with the same breathless, "I'm just happy to be here" enthusiasm that has made Paul a Hollywood treasure for decades. Honestly, if you closed your eyes during their 2023 Fox Sports interview, you literally wouldn't be able to tell which one was the Marvel star and which one was the kid.

The Mystery of Jack Sullivan Rudd

So, who is he?

Jack was born in 2006, the first child of Paul Rudd and his longtime wife, Julie Yaeger. While some celebrity kids are out here launching skincare lines or reality shows by the time they hit puberty, Jack has stayed mostly off the grid. He grew up primarily in Rhinebeck, New York, far away from the paparazzi-heavy streets of Los Angeles.

His childhood was surprisingly normal. In fact, it was so normal that for a long time, Jack didn't even realize his dad was a famous actor. Paul famously admitted that when Jack was about four or five, they walked past a movie poster in a theater lobby. Since Paul didn't want to be that guy who sits his toddlers down to watch their own IMDb credits, he just let Jack believe he worked at the theater.

"I never corrected him," Paul told Willie Geist. Jack spent years thinking his dad was just a really dedicated employee at the AMC Loews. It wasn't until he was around 15 that he finally put the pieces together. Imagine finding out your "theatre manager" dad is actually Ant-Man.

That Viral Super Bowl Energy

If you know anything about Paul Rudd, you know he is a die-hard Kansas City Chiefs fan. He grew up in the KC area, and he has passed that obsession down to Jack like a family heirloom.

The world really got to meet Jack Sullivan Rudd during the Chiefs' recent Super Bowl runs. In 2023, after the Chiefs beat the Eagles, the duo did an on-field interview that went nuclear on TikTok. While Paul was his usual charming self, Jack stole the show by gushing over Patrick Mahomes.

"I just want to thank Patrick Mahomes for existing... I cannot believe he's a real person," Jack said.

The internet lost its mind. Not because he was a fan, but because his cadence—the specific way he pauses, his hand gestures, that "Rudd-ish" wit—was a carbon copy of his father. By the time they showed up at Super Bowl LVIII in Las Vegas in 2024 (and again at the 2025 game in New Orleans), Jack had officially become the unofficial mascot for "Good Genes."

More Than Just a Mini-Me

Despite the "clone" labels, Jack is very much his own person. We know a few things about him through Paul’s various late-night couch stories:

  1. He's a Hot Sauce Masochist: Like his dad, Jack is a fan of the YouTube show Hot Ones. After Paul appeared on the show, he brought the "Mega Death" sauces home. Jack and a friend tried to do the challenge themselves and, according to Paul, it "took them down for about three days."
  2. He has a Great Bullshit Detector: When Paul told a then-nine-year-old Jack he was going to be a superhero called Ant-Man, Jack’s response wasn't "Wow, Dad!" It was: "I can't wait to see how stupid that'll be."
  3. He’s a Big Brother: He has a younger sister, Darby, who was born in 2010. By all accounts, the Rudd family is incredibly tight-knit, often seen at sporting events or grabbing coffee in upstate New York.

What’s Next for Jack?

As of 2026, Jack is 19 years old. He’s officially reached that age where people start wondering if he’s going to follow the "nepo baby" path into acting.

So far? There’s no sign of it.

He doesn't have a public Instagram (at least not one we can find), and he isn't cropping up in indie films or modeling campaigns. He seems content just being a college-aged kid who happens to have a very famous, very ageless father.

If you're looking for more info on the Rudd family, keep an eye on the Chiefs' sideline. That’s usually the only place you’ll catch a glimpse of them. It's refreshing, honestly. In a world where every celebrity kid is trying to be a "brand," Jack Sullivan Rudd seems perfectly happy just being a fan in a jersey, losing his mind over a touchdown right next to his dad.
