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. For her family was the priority.

She is definitely a role model. 

Sylvester and Sasha

All the time when Seargeoh’s father was grinding to make a name in Hollywood, there was one lady who never left his side: Sasha Czack.

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, Sasha (Alexandra Jane Czack) was also interested in acting from a young age. Sasha is known for her appearance in C.B.S. Network’s Love For Life.

Even though she has exceptional roles to her credit, people know Sasha as the ex-wife of Sylvester Stallone.

Sylvester and Sasha met each other while during their work. Their infatuation was instant, and love followed without taking much time.

Sasha’s loved him a lot. She gave up her career and happily supported Sylvester to achieve his goals. The love between them grew much more than before, and the couple finally tied the knot on 28 December 1974.

Two years later, they welcomed a beautiful baby boy, Sage Stallone. The happiness was beyond the limit when they had their second-born, Seargeoh Stallone, in 1979.

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

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.

Sylvester said “Her dreams and aspirations have been rechanneled 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.”
