Early Life And Background

Cassandra Marino was born on June 10, 1980, in Los Angeles, California. She grew up during a time when her father, Caitlyn Jenner, was known to the world as Bruce Jenner — a celebrated Olympic gold medalist who became a national hero after winning the 1976 decathlon at the Montreal Games. Her mother, Chrystie Crownover (now Chrystie Scott), was Caitlyn’s first wife and a former actress who appeared in a few television shows.

Cassandra’s childhood was very different from that of her younger siblings. She spent her early years away from the cameras, long before the Kardashian-Jenner empire was born. Her parents divorced in 1981 when she was just a year old, leading her to be raised mostly by her mother in a quiet and stable environment. Even though Caitlyn’s later marriages and fame brought public attention to the family, Cassandra maintained a grounded, low-profile lifestyle.

The couple had two children — Burt and Cassandra — before their separation in 1981. Despite the divorce, both parents continued to support their children. Chrystie went on to lead a private life, while Caitlyn’s later marriages introduced Cassandra to a large, blended family that would eventually become one of the most famous in Hollywood.
