Who is Killian Marcus Nielsen, Brigitte Nielsen’s Son and Where Is He Now?

Killian Marcus Nielsen is a man of American and Danish descent. He is well-known for being the son of Brigitte Nielsen, a famous Danish actress, and Mark Gastineau, an American football player. Killian managed to stay out of the public eye until his twenties when the media discovered his identity and began to investigate his life.

Before his reveal, his mother had kept him away from the public eye, hoping he would lead a normal life. Nowadays, Killian is making a name for himself by featuring in an Italian reality TV show and carving out his path in life.

Killian Marcus Nielsen was Born 33 Years Ago

Killian Marcus Nielsen was born on the 15th day of December. This means he is 33 years old at the moment. An American citizen, he was born in the USA to an American father named Mark Gastineau and a Danish mother named Brigitte Nielsen. He spent some time in the USA as a child before relocating to Italy with his mother after his parents parted ways.

A lot of information about Killian’s childhood is not available to the public. This is because while he was growing up, he was carefully shielded from the public by his mother who raised him. He was so shielded from the public that even his step-sister, Brittny Gastineau, didn’t even know he existed for a long time. However, as he grew into an adult, more details about him began to emerge.

 

What is Killian Marcus Nielsen’s Real Name?

In recent times, there have been some discussions about what Killian’s real name is. This is because different media reports have referred to the man by different names in the past. Some media reports refer to him as Killian Gastineau while others refer to him as Killian Marcus Nielson. So, readers have asked which one is real.

The truth is, that Killian is often referred to as Killian Gastineau concerning his father’s name. However, others refer to him as Killian Marcus Nielson because this was the name he was known by for many years while growing up with his mother. Recall that Killian grew up with his mother and had very little contact with his dad until he was an adult. So, his mother’s surname stuck with him.

At the moment, it is not clear what surname sits on his official passport but most reports, including those on Italian papers, refer to him as Killian Marcus Nielson.

What Happened Between Killian Marcus Nielsen’s Parents?

The couple first met at the Super Bowl that year and took interest in each other. At the time, they were already famous names; Gastineau was already a renowned American football star and Brigitte was a famous model and actress.

When they started dating, their romance made headlines because Brigitte had just divorced her ex-husband, Sylvester Stallone, and Gastineau was separated from his wife Lisa but was still finalizing their divorce. Brigitte’s family adored Gastineau so much and it appeared everything was going very smoothly. Soon after they started dating, they got engaged and this caused another hysteria in the papers.

In December 1989, Brigitte and Gastineau welcomed their son Killian Marcus Nielsen. Killian was born on December 15 of that year. It appeared that the couple would surely go ahead to tie the knot as man and wife considering the arrival of their baby. However, this was not to be because months later in 1990, the couple broke up and parted ways.

Speaking about their breakup later, Brigitte explained that she faced physical abuse at the hands of Gastineau. According to her, it happened several times and she just could not take it anymore.
