Everyone knows who Sylvester Stallone is but not that many people are aware that the action star has a 40-year-old son named Seargeoh.
Seargeoh Stallone is, still to this day, a mystery to many "Rocky" fans around the world who have seen happen to have seen him in the second movie, in 1979.
Although his father is a household name in Hollywood, thanks to all the action and drama movies he was in, the same can't be said about Seargeoh.
Seargeoh was born in 1979. His grandfather was Frank Sr. Stallone, an Italian-American hairdresser, and polo fan, while his grandmother, Jackie Stallone, was an Astrologer and a promoter of women's wrestling.
With a father like Sylvester Stallone and a mother like Sasha Czack, an actress famous for "Long Lost Love," great things were expected.
Seargeoh portrayed the role of Rocky Balboa Jr. in "Rocky II," that was his last part ever since he was diagnosed with autism in 1982, at the age of three.
He used to be called 'Sly's Silent Son' because he wouldn't say a single word as a child.
Due to being away from the spotlight, many people started confusing him with his older brother, Sage Moonblood, who passed away at age 36, in 2012, due to heart disease.
Moonblood was famous for playing the role of Robert Balboa in the 1990 movie "Rocky V" and went on to appear in other projects such as "The Evil Inside Me" and "Moscow Zero."
Not much else is known about Seargeoh's whereabouts because he rarely leaves the house and his father doesn't like to comment on the family's private life.
People have practically forgotten about him, so tabloids don't bother chasing him since he doesn't really mingle with others.
As far as everyone knows, he's currently single and doesn't have a job, being supported by his Stallone, whose net is worth $400 million.
The action movie star has been keeping himself busy by filming "Rambo V," which is expected to hit theaters in the fall of 2019, and he couldn't help but share an image on his Instagram page to commemorate the occasion.
