Sylvester Stallone's 5 Kids: Everything to Know

Sylvester Stallone is one proud dad.

The legendary Rocky and Rambo actor has five kids: sons Sage and Seargeoh from his first marriage with actress Sasha Czack, and daughters Sophia, Sistine and Scarlet from his marriage to former model Jennifer Flavin.

"I make a much better father and husband now than I could have earlier ... I sometimes think all men should wait till they're 50 to settle down," Stallone said in 2007, referring to his personal and parenting struggles while raising Sage and Seargeoh. "You figure out that it's not your work and successes that count, but the kind of life you make for yourself and the people who know you."

Despite the learning curve, Stallone and his eldest child were on good terms before his death in 2012. "I got a lot of things out. We broke into tears a few times," Sage told PEOPLE in 1996 about how working on Rocky V changed their relationship for the better. "After the film, everything changed. We’d do anything for each other."

The actor echoed a similar sentiment about family shortly after Flavin filed for divorce in August 2022 and they reconciled a month later. "Sometimes I put the work ahead of [my family], and that is a tragic mistake which won't happen again," he told The Hollywood Reporter.

Since then, Stallone, Flavin and their daughters have shown a different side of their family on their reality TV show, The Family Stallone.

Here's everything to know about Sylvester Stallone's kids: Sage, Seargeoh, Sophia, Sistine and Scarlet.

Sage Moonblood Stallone

Stallone and Czack welcomed son Sage Moonblood on May 5, 1976, in Los Angeles. In the early years of his life, Sage followed in his dad's footsteps, even playing Rocky's son in Rocky V.

Sage, who had a keen interest in filmmaking, studied it for a year at the North Carolina School of the Arts before moving back to L.A. to act alongside Stallone in the 1996 thriller Daylight. Despite working with his famous dad, the two had different personalities.

"Sage has chosen an entirely different route," Stallone told PEOPLE in 1996. "He's interested in a different type of filmmaking. And he avoids the gym like the plague."

Sage agreed and added, "People call me a hermit. But I'm happy."

On July 13, 2012, Sage died unexpectedly, with reports later confirming that he died of heart disease.

"Sage was a very talented and wonderful young man; his loss will be felt forever," a representative for Stallone said at the time.

In Stallone's Netflix documentary, Sly, which premiered in November 2023, the actor made a few rare comments about Sage. He also confirmed that the tumultuous relationship between Rocky and his son in Rocky V was "unfortunately" art imitating life.

"Unfortunately, you put things before your family. And the repercussions are quite radical and devastating," he said.

Seargeoh Stallone, 44

Stallone and Czack welcomed their second son, Seargeoh, in 1979. At age 3, Seargeoh was diagnosed with autism and has since lived a life mostly out of the spotlight.

In 1985, Stallone and Czack established a research fund administered under the National Society for Children and Adults With Autism. "Sasha does the hard, in-the-trenches warfare," Stallone told PEOPLE for a 1985 cover story. "I use my films to have premieres that raise money for the fund."

Sophia Rose Stallone, 27

Stallone and Flavin welcomed daughter Sophia Rose on Aug. 27, 1996, in Miami. To correct a congenital malformation of a heart valve, Sophia underwent heart surgery at just 2 months old and again in 2012.

In a 2012 interview with Paris Match, Flavin said that of all three of their daughters, Sophia takes after her dad the most. "They have a very special bond, they think alike and even have the same gestures. Sophia is the love of his life," she shared.

Sophia graduated from the University of Southern California in 2019 with a degree in fashion and currently hosts the Unwaxed podcast with her sister Sistine. She also runs a digital book club on Instagram called Favorite Book Club.

Sophia celebrated her 26th birthday just days after her parent's divorce went public. After telling PEOPLE that the couple is "amicably and privately addressing these personal issues," Stallone posted two family photos on Instagram in honor of his daughter.

The Rocky star's caption read, "A VERY HAPPY BELATED BIRTHDAY TO MY VERY SPECIAL DAUGHTER, SOPHIA!!!"

Sistine Rose Stallone, 25

Sistine Rose was born on June 27, 1998, in L.A. A budding model like her mother, she signed with IMG Models in 2016 and has since walked in several fashion shows, including one for Chanel later that year. She was also named a "fresh face to watch" by Vogue, and later starred in a Love magazine advent calendar photoshoot.

Sistine has also tried her hand at acting, making her debut in the 2019 horror film 47 Meters Down: Uncaged. She starred in 2021's Midnight in the Switchgrass alongside Bruce Willis, Megan Fox, Machine Gun Kelly and Emile Hirsch.

"He would help me read for all of my auditions in the beginning," Sistine told PEOPLE of her dad in 2019, though her manager advised against it due to Stallone's easily recognizable voice.

Scarlet Rose Stallone, 21

Stallone and Flavin welcomed Scarlet Rose on May 25, 2002, in L.A. Stallone regularly shows love to his youngest daughter on social media. "Happy birthday to our amazing daughter, Scarlet," he wrote in a heartfelt tribute for her 19th birthday. "You are talented, humble and generous to all. We love you beyond words."

Scarlet, who graduated high school in 2021, seems to have inherited her father's athleticism: a video posted on Instagram in 2016 shows Scarlet winning her division at a track and field competition, with Stallone playfully referring to her as "The Flash." When Scarlet and her sisters served as Miss Golden Globes in 2017, she told PEOPLE that her personal style aesthetic is "tomboyish."

In February 2024, Scarlet made her New York Fashion Week debut when she walked in the Tommy Hilfiger show, and her dad was there to cheer her on.

“What can I tell you, I am a very proud father,” Stallone told Fashion Network at the show as he showed off photos he'd taken of Scarlet on his phone.
