Seargeoh was born on August 18th, 1979, in Los Angeles, California, USA. Based on his date of birth, he is a Leo.

Leo males are protective, warm, exceptionally helpful, fiercely loyal, and very generous; however, they are prone to jealousy and possessiveness.

Sylvester and Sasha called him “silent genius” as Seargeoh wouldn’t speak at all. They sought professional help as the kid was having difficulty communicating.

After a diagnosis in 1982, the experts informed the parents that their youngest son, Seargeoh, was autistic at three.


Sylvester and his wife, or for that matter, no one could believe what was to come. Seth Stallone was quite one, he wouldn’t speak at all. Just like any normal parents, it wasn’t something they were aware of. As Sasha and Sylvester sought help, they found out that Seargeoh Stallone was autistic.

No doubt, Sasha and Sylvester were heartbroken. They decided to shoulder the responsibility. Later on, it led to their divorce. After the separation of his parents, Seargeoh started living with his mother.

Seargeoh appeared in a movie, Rocky II, shortly after his birth. He was in the film as the infant son of Rocky Balboa.

Because of his disability, Seargeoh could not achieve much as Sylvester wanted for his younger son.

Seargeoh Stallone Autism

Autism is also known as ASD (Autism Spectrum Disorder). Autistic people have problems communicating, socializing, and developing interpersonal relationships. 1 in 59 children suffers from it

The diagnosis broke the hearts of his parents. In a few interviews, Sasha said,

We both broke down. I knew that Sly couldn’t get as involved because of his work. We do what we have to do. So I just said, ‘Give me the money, and I’ll take care of it.

Both parents actively started a research fund that was administered under the National Society for Children and Adults With Autism. Sasha was actively involved. However, Slyvester worked on raising funds.

Despite the autistic condition, Seargeoh Stallone could draw, write letters, and repeat certain words. Still, communication was a big task for him, and so was understanding for his close ones. Seth’s parents did everything they could to give him a normal life.


Sylvester Stallone (father)

If there is one person who probably doesn’t need any introduction, is it Sylvester Stallone? Sure, some people will not know him by name, but if someone speaks to you about “Rambo” and “Rocky,” you can recall his face.

Sylvester Enzio Stallone is the son of Frank Stallone Sr and Jackie Stallone. Creativity and acting were in his blood. His father, Frank, was a hairdresser, a writer, and an actor. His mother, Jackie Stallone, was an astrologer, a dancer, and a promoter of Kaybafe wrestling.

Sly’s career took off as an actor; however, few know that he is an equally talented actor, screenwriter, director, and producer. He has worked in over fifty-five films, most of which were big box office hits.

Some of his famous filmographies are Rocky (1976), F.I.S.T. (1978), Paradise Alley(1978), First Blood(1982), Rambo: First Blood II(1985), Demolition Man(1993), Rambo: Last Blood (2019), etc.

Stallone placed himself on the Hollywood Walk of Fame in 1984.

There’s so much one can learn from Sylvester Stallone. Even at the age of 74, he is fit and cautious about his health. It won’t be wrong to say that the 1.77m tall Sylvester Stallone is as Macho man as he was in the 1970s.

Sasha Czack (mother)

Sasha Czack is a Pennsylvania native. She was born in 1950. Her full name is Alexandra Jane Crazy. She graduated from Notre Dame with a degree in Media Studies.

While she may not have the fame Sylvester earned, she has been in soap operas such as “Love of Life.” In Rocky III, she appeared in a minor role as a woman exercising in a gym.

One of the reasons her career did not take off as an actor was because of her caring nature. She sacrificed her career for Sylvester and later for Seargeoh. Her family was the priority.

She is definitely a role model.

Sylvester Stallone started his acting career in 1969. By the late 70s, Sylvester’s popularity had paved its way to the top. On the other hand, from a young age, Sasha (Alexandra Jane Czack) was also interested in acting. Sasha is known for her appearance in C.B.S. Network’s Love For Life.

Even though she has notable roles to her credit, her identity is known for her marriage to Sylvester.

Both met at work.

Sasha’s loved him a lot. She gave up her career and happily supported Sylvester in achieving his goals. The couple finally tied the knot on December 28, 1974.

They welcomed a beautiful baby boy, Sage Stallone, in 1976 and Seargeoh Stallone, in 1979.

Even though the couple has had a more or less rocky relationship which almost ended in 1978, after ten years of marriage, Sasha filed for a divorce based on mutual understanding.

The reason for their divorce was more or less Seargeoh’s medical condition. While Sylvester was always away and busy with the work schedule, Sasha, on the other hand, was entrenched and fully committed to the research.

In an interview with People Magazine, Sylvester said, “Her dreams and aspirations have been re-channeled into dedicated research. She is a driven person in that area. All of her priorities are geared toward finding a cure. There is no fun in the future that way.”

After the failure of the first marriage, both Sylvester vowed to be Brigitte Nielson’s (actress and model) husband on December 15, 1985. 

The marriage did not last longer than two years. Later in May 1997, Sylvester married his present wife, Jennifer Flavin Stallone.

He has three daughters: Sophia, Sistine, and Scarlet Stallone, with his current wife.

Rumors about his death

Sylvester Stallone is still alive and well. There was a rumor circulating on Facebook and Twitter claiming the actor had died at 71 after a fight with prostate cancer.

However, the actor and his brother Frank Stallone turned to social media on Monday to reassure the public of this truth. Similarly, the scam was pretty evident.

According to IMDb, Stallone has been steadily working, most recently appearing in an episode of “This Is Us” and filming multiple movies. Perhaps that’s why, in an Instagram post, he seemed to ignore it.

Additionally, “Alive and well and happy and healthy,” he said in the message, “please ignore this stupidity.”

Similarly, “Rumors that my brother is deceased are false,” his sibling stated. What kind of wicked, deranged, and nasty mind thinks up such things to post? “I’m very defensive of my older brother, and I don’t find any humor in this bogus post today about my brother’s demise,” he said on Twitter, adding, “People like these are mentally insane and don’t deserve a place in society.”

Similarly, Seargeoh’s mother also got married for the second time. She tied the knot with the Primetime Emmy Award Winning re-recording mixer, Rick Ash. Unfortunately, her second marriage ended on bad terms too.
