Arnold Schwarzenegger's secret son Joseph Baena has reportedly been "shunned" by the actor's other children.
Earlier this month the Terminator star opened up about how his affair with his housekeeper and his resulting love child blew his family apart.
Joseph is the youngest of Arnold's five children. He fathered him with his housekeeper Mildred Baena while married to Maria Shriver who is the mother of his other four kids.
Arnold's eldest daughter Katherine Schwarzenegger, 33, didn't invite Joseph to her wedding to Chris Pratt in 2019 although her half-brother sent his well-wishes.
And now it's been claimed the children "didn't love" Joseph as they attended their dad's FUBAR premiere separately.
Joseph is a bodybuilder, fitness model and an actor, who now enjoys a close relationship with his famous dad.
But Arnold's children with Maria - Katherine Schwarzenegger, 33, Christina Schwarzenegger, 31, Patrick Schwarzenegger, 29, and Christopher Schwarzenegger, 25, - don't seem so sure about welcoming Joseph into the clan.
In 2019 when Katherine married Chris Pratt she reportedly didn't invite her half brother and he resorted to sending the couple his congratulations on Instagram.
After the lavish wedding in Montecito, California, Katherine took to Instagram to share a snap from the day.
Joseph commented: "Congratulations!" and posted two love hearts and a bottle of champagne emoji.
A source told Page Six at the time that Katherine and her sister Christina "have really no relationship with Joseph".
But despite the relationship appearing frosty, the kids already knew Joseph as the housekeeper's son before his mother's relationship with their father was exposed.
"He grew up around them," a source told Page Six at the time. "He was a regular at the mansion in Pacific Palisades, where the family lived from 1986 until 2003."
Katherine was also criticised on National Siblings day when she shared childhood pictures of her three siblings - but not Joseph.
Meanwhile, Arnold has acknowledged how complicated the relationship is between his children.
"He's [Joseph's] terrific and he totally understands the situation," the dad-of-five told Howard Stern in 2015.
"So, it all has worked out. It's a very tough situation for him. It's a very tough situation for my kids. Very tough situation for my family. It was tough for everybody. But it has happened and now we have to figure it out, right?"
Last month, the family all turned out for the LA premiere of Arnold's new Netflix series FUBAR.
But Joseph walked the red carpet alone and reportedly didn't meet up with his half-siblings at the event, according to the Daily Mail.
Mirror has contacted representatives for Arnold, Joseph, Katherine and Patrick for comment.
Schwarzenegger opened up about the affair he had with his housekeeper in 1996 in his new Netflix documentary.
In 1996, Arnold had an affair with housekeeper Mildred Baena, who fell pregnant and welcomed a child nine months later, which happened to be just five days after Maria and Arnold's son Christopher was born.
At the time, nobody knew that Mildred's son was actually Arnold's child, or that Christopher was his half-brother.
But as Mildred's son Joseph grew up, she noticed that he looked a lot like the famous actor she had an affair with months prior to welcoming her son.
It wasn't until 2010 when Joseph was 13 that he learned who his biological dad was, which came when the media announced it.
Arnold said his "heart stopped" when Maria confronted him about the affair in a counselling session.
"One day, the counsellor said, ‘Today Maria wants to be very specific about something. She wants to know if you’re the father of Joseph’.
“I thought my heart stopped. And then I told the truth," he says in the new three-parter.
He then went on to reveal how he was honest, admitted that Joseph was his son and that Maria was "obviously crushed by that".
Speaking about his son Joseph in the docuseries, Arnold added: "In the beginning, I really didn’t know, but the older he got, the more it became clear to me.
"It was then just a matter of, ‘How do you keep this quiet?’."
Arnold then admits that the affair he had with the housekeeper was his biggest "failure", adding that he has "caused enough pain" for his family" and noting how "everyone had to suffer".
"Maria had to suffer, the kids had to suffer, Joseph, his mother, everyone. I'm going to have to live with that for the rest of my life," he added.
Following Arnold admitting to having an affair with their housekeeper, Maria filed for divorce from the bodybuilder after 25 years of marriage in 2011.
The couple were separated for almost a decade before their divorce was officially finalised in December 2021.
Meanwhile, Joseph's relationship with his dad appears to be flourishing and he said that he is "starting to catch up" to his father lifting weights and added that he is the "best training partner" in the gym.
"He's the best training partner even though I'm starting to lift a little ... I'm starting to catch up with the weights," he said. "He pushes me so much in the gym and we love training together."
Joseph spoke about his dad whilst being interviewed by Extra at the FUBAR premiere.
Joseph said that Arnold is "really supportive" and pushes him to "work really hard," including encouraging him to make projects his own.
"His main piece of advice has always been, do the reps - and it sounds just like the gym. But it really makes sense because it's all about practice, practice, practice," he said.
