You know him as Rocky Balboa or Rambo, the guy who takes hits and just keeps moving forward. But off-screen, Sylvester Stallone’s life hasn’t just been about red carpets and blockbuster sequels. It’s been about a family that is way more complicated and tight-knit than the tabloid headlines usually suggest. Honestly, if you’re trying to figure out how many children does Sylvester Stallone have, the number is five.
Five kids. Two sons from his first marriage and three daughters from his current one.
But it’s not just a simple list of names. There is a lot of history there—some of it pretty heartbreaking and some of it surprisingly normal for a guy who once lived in his car.
The First Chapter: Sage and Seargeoh
Sly’s first marriage was to Sasha Czack back in 1974. This was before the Rocky fame really exploded. They had two boys together, and their stories couldn't be more different.
Sage Moonblood Stallone was the firstborn. If you’re a fan of the franchise, you definitely remember him. He played Rocky’s son in Rocky V. You know, the kid who felt like his dad cared more about Tommy Gunn than his own family? Turns out, some of that tension on screen was real. Sage later admitted that when he was yelling at his dad in those scenes, he was tapping into real-time feelings about Sly being away at work.

They eventually patched things up and even worked together again on the movie Daylight. Sadly, Sage passed away in 2012. He was only 36. At first, the internet did what it does best and started rumors about drugs, but the coroner later confirmed it was actually a heart condition called atherosclerosis. It absolutely wrecked Stallone. He’s talked about how there’s no greater pain than losing a child, and you could see that grief transform him into a much more family-focused guy later in life.
Then there’s Seargeoh Stallone.
He was born in 1979. He’s the most private member of the entire Stallone clan. When he was about three years old, he was diagnosed with autism. Unlike a lot of Hollywood families at the time who might have kept things quiet, Sly and Sasha were pretty open about it eventually. Seargeoh actually appeared as an infant in Rocky II, but he’s stayed completely out of the spotlight since then. He lives a quiet life away from the cameras, and the family is fiercely protective of his privacy.
The "Rose" Trio: Sophia, Sistine, and Scarlet
After a very public and somewhat chaotic marriage to Brigitte Nielsen (no kids there), Stallone met Jennifer Flavin. They’ve been together forever—well, since 1997, which is basically forever in Hollywood years. They have three daughters, and they all share the middle name "Rose."
If you’ve scrolled through Instagram or watched The Family Stallone on Paramount+, you’ve seen them.

Sophia Rose Stallone
The eldest daughter, born in 1996. Sophia is often considered the most like her dad in terms of personality. She’s a bookworm who runs a digital book club and co-hosts the Unwaxed podcast. But things weren't always easy for her. She was born with a heart defect and had to have major surgery when she was just a tiny baby. She actually had to go under the knife again in 2012, the same year her half-brother Sage died.
Sistine Rose Stallone
Born in 1998, Sistine is the one who really bit the acting and modeling bug hard. She’s walked for Chanel and was in the movie 47 Meters Down: Uncaged. She’s got that classic Stallone grit but leans more into the fashion world. She’s also the co-host of that Unwaxed podcast with Sophia, where they basically roast their dad and talk about dating in LA.
Scarlet Rose Stallone
The baby of the family, born in 2002. She’s recently started dipping her toes into acting, appearing alongside her dad in the series Tulsa King. For a long time, she was just the "quiet one" who did track and field in high school, but she’s definitely coming into her own now.
Why the Stallone Family Dynamic Matters
It’s easy to look at a guy like Sly and think he’s just an action star. But when you look at the reality of how many children does Sylvester Stallone have, you see a guy who has dealt with the highest highs and the absolute lowest lows.

He’s admitted that in the 80s and 90s, he was a "migratory worker." He was never home. He was always on a set in some far-off country. He’s been very vocal lately about the fact that he regrets putting work before his family during those early years. You see that reflected in his reality show. He’s almost overcompensating now, being the overprotective "Italian dad" who scares off his daughters' boyfriends.
- Sage: The tragic loss that changed Sly's perspective on life.
- Seargeoh: The son who taught the family about patience and privacy.
- The Daughters: The "second chance" where Sly actually showed up to be a present father.
He basically had two different parenting lives. One where he was a struggling actor becoming a superstar, and another where he was an established icon trying to fix the mistakes of the past.
What You Should Take Away
Most people asking about Stallone’s kids are usually surprised by two things: the death of Sage and the fact that there’s a second son who isn't in the public eye. The daughters get all the press because they’re active on social media and have a TV show, but the full picture is much more nuanced.
If you’re looking to follow the family’s journey today, the best place is actually their reality show. It’s surprisingly grounded. You see Sly doing things like taking his daughters to self-defense classes or complaining about their outfits. It’s a weirdly humanizing look at a guy who we usually only see holding a machine gun.
Practical Insight: If you're researching celebrity family histories like this, always cross-reference with their own social media or long-form interviews. In Stallone's case, his Netflix documentary Sly provides a lot of the "why" behind his relationship with his kids, especially the parts he regrets. It’s a masterclass in how success often comes at a high personal cost.
