Sylvester Stallone Is a Father of 5 — Get to Know His Kids

Updated on 11/2/2023 at 1:50 PM

Sylvester Stallone is one of the most recognized actors in the industry. His breakout role came in 1976 when he starred in "Rocky," which was such a big hit that it received 10 Oscar nominations and went on to inspire a whole film franchise. It also led Sylvester to land his role as John J. Rambo in 1982 action film "First Blood," which, similarly to "Rocky," resulted in a number of sequels that turned Sylvester into a pop-culture icon. Even decades later, he's still dominating Hollywood with parts in the Creed, Expendables, and Guardians of the Galaxy franchises. However, one of the actor's biggest roles in life is being a father to his five kids.

Sylvester's family is super supportive of his acting career. His wife, Jennifer Flavin, a successful model and entrepreneur, frequently attends Sylvester's movie premieres, and so do the couple's three daughters: Sophia Rose, Sistine Rose, and Scarlet Rose Stallone. Whenever the trio aren't joining their parents on the red carpet, though, they're off pursuing their own acting and modeling projects. The family's reality TV series, "The Family Stallone," brings them all together to show off what goes down with them at home.

Leading up to their show's May 2023 premiere on Paramount+, Sylvester's wife and three daughters appeared on "Today," where the trio opened up about what it's like dating when their dad is famously known to the world as Rocky Balboa and Rambo. "It's very difficult," middle daughter Sistine shared. "He's quite intimidating to most, and most of the time when they come over to meet the parents, they don't necessarily return, simply because he's just so scary." Sylvester defended himself, saying that it's because "I don't trust their intentions. Because I know men."

The "Tulsa King" star also had an oldest son named Sage Moonblood Stallone, whom he shared with first wife Sasha Czack, who dabbled in acting and filming before he died in 2012. While four of Sylvester's kids have been in the spotlight, the actor's second son, Seargeoh Stallone, whom he also shares with Czack, has lived a quiet life out of the public eye.

Sage Moonblood Stallone

Sylvester and Czack's first son, Sage Moonblood, was born on May 5, 1976, in Los Angeles. At just 14 years old, Sage made his acting debut in the 1990 film "Rocky V" as his father's onscreen son, Rocky Balboa Jr. After getting his first taste at acting, Sage went on to study filmmaking at the University of North Carolina School of the Arts.

In 1996, he and his father became costars once again when they both appeared in the film "Daylight." Sage also appeared in a number of other films, like "Chaos," "Moscow Zero," and "Promises Written in Water."

One of Sage's most notable projects came in 2006 when he directed, wrote, and produced the short film "Vic," which earned him the best new filmmaker award at the Boston Film Festival that year. In 2010, he also appeared in the short film "The Agent." The role marked Sage's final acting project before he died on July 13, 2012.

"Sage was our first child and the center of our universe and I am humbly begging for all to have my son's memory and soul left in peace," the actor told TMZ at the time. It was revealed weeks later that Sage died of heart disease, per People.

Seargeoh Stallone

Sylvester and Czack also share a son named Seargeoh. He was born three years after Sage in 1979, although his exact birth date is unknown. At just 3 years old, Seargeoh joined his father on the cover of People in 1982 around the same time that "Rocky III" was released.

In a June 1985 interview with the magazine, Sylvester revealed his son was diagnosed with autism, which inspired him and Czack to launch a research fund under the National Society for Children and Adults With Autism. Sylvester said he used his film premieres to raise money for the fund.

Sophia Rose Stallone

Sylvester and his third wife, Flavin, welcomed their first daughter, Sophia, on Aug. 27, 1996, in Miami, FL. After Sophia graduated from the the University of Southern California in May 2019, she went on to launch a podcast with her sister, Sistine, called "Unwaxed," which is available to stream on YouTube, Spotify, and Apple Podcasts. According to the podcast's description on YouTube, the show is named after the idea that the sisters are "baring it all" by discussing everything "from adulting to single life."

Besides that, Sophia runs the Instagram account @favoritebookclub, which is dedicated to book recommendations and reviews. Apparently, Sophia got her love of reading from her dad. In a 2012 interview with Paris Match, Sophia's mom said that like Sylvester, Sophia "has read nearly all of Shakespeare's books."

Sistine Rose Stallone

Sistine is Sylvester and Flavin's second oldest daughter. She was born on June 27, 1998, in Los Angeles. Despite coming from a famous family, Sistine has made a name for herself by becoming a successful model and actor. In December 2016, she walked the runway at Chanel's annual Métiers d'Art show. She also appeared on the November 2017 cover of Elle Russia and has continued her rise to stardom by appearing in the 2019 horror film "47 Meters Down: Uncaged" and the 2021 crime thriller "Midnight in the Switchgrass." She's also the cohost of the "Unwaxed" podcast with her sister, Sophia.

Scarlet Rose Stallone

Scarlet, who is the youngest daughter of Sylvester and Flavin, was born on May 25, 2002, in Los Angeles. She graduated high school in June 2021. At the time, her father celebrated her milestone by posting a photo with his family on Instagram. "Congratulations on graduating high school to our wonderful daughter SCARLET!" Sylvester captioned the shot, which showed the actor, his wife, and their three daughters posing for a group photo.

If you're wondering what kind of student Scarlet was in high school, she was apparently a track and field star. Scarlet still makes sure to make the gym part of her daily routine. In August 2020, her trainer Kevin Mejia told Hollywood Life that Scarlet and Sophia "conquer some of the toughest exercises in the gym with ease."

"We focus sessions on consistent toning and core work," Mejia said about the sisters' workouts. "They love the bands, but never shy away from weights."

Scarlet may not be acting or modeling like the rest of her family, but she does make sure to support them by attending their red carpet events and premieres whenever she can.

She also has a boyfriend, according to "Today," who's already met her father. "Yes, and he was great meeting him," Scarlet told the show. "Now they're best friends." Sylvester even joked, "We have matching tattoos, it's great."
