Oh yes it has been quite the week for the Gastineau family, and I have all the juicy details for you and trust me they are good so you are going to want to keep reading.

Last week Brittny Gastineau met her half brother Killian Marcus Gastineau, whose mother is actress Bridgette Nielsen, for the first time, doesn’t sound too crazy right> Well get this Marcus, as he is called, is 20 years old. Yep for two decades the half siblings had not ever met. Now that sounds like a perfect reality TV moment if I ever saw one, too bad Brittny doesn’t have her reality show anymore.

Was daddy Mark Gastineau keeping a secret son this whole time, nope not at all. According to Brittny, she has knownabout Marcus since she was a child, but considering that they lived across the world from each other, he lives in Italy, she lives in Los Angles, it was an out of sight out mind situation.

Bridgette Nielsen and Mark Gastineau, a former New York Jets player, had a love affair years ago. In fact Mark left Lisa Gastineau so he could be with Bridgette. In an interesting turn of events it was actually Lisa and Bridgette’s somewhat friendly run in at Ivana Trump’s wedding last April that started the half siblings on the road to meeting.

So what do we know about Killian Marcus Gastineau? Well he lives in Italy, where he works for a wine and champagne company. He is blond, very tall and looks like Bridgette and that is about it. However I am sure we will learn plenty more about the newest Gastineau in the days to come.

Brittny Gastineau is a socialite and star of the reality TV show Gastineau Girls, which costarred her mother Lisa. I have a video clip from the show below, along with some pictures of Brittny.
