The children of Maria Shriver and Joseph Baena, Arnold Schwarzenegger’s lookalike son, are rumored to have a “family rift” in the Schwarzenegger household.

At the launch of his new Netflix series “FUBAR,” the 75-year-old Terminator star posed for pictures with his children Katherine, 33, and her husband Chris Pratt, as well as Christina, 31, and Shriver. Although he attended the premiere alone, Schwarzenegger’s son Joseph Baena, whom he fathered with his former housekeeper Mildred Baena, was present.

Schwarzenegger and Joseph “are very close,” according to a family insider, but Shriver and her kids still don’t interact with Baena. The source said, “To be honest, the other kids don’t love Joe. It’s unfortunate since Arnold has always treated him equally to all of his other children. But for some reason, the other kids blame Joe for the affair.”

Joseph Baena showed his pride in his father with a selfie at the premiere, wearing a gold chain necklace, black jacket, black jeans, and a white button-up shirt. He captioned the photo, “I give FUBAR 2 thumbs up!!! Had an amazing time last night at the FUBAR premiere! In my unbiased opinion, FUBAR is a hilarious, action-packed show that will have you on the edge of your seat the entire time!”

One of Baena’s Instagram followers commented, “It’s disgusting how you are treated, man, by your own blood. Completely ignored due to something out of your control. Is it racial hostility? Who knows. At the end of the day, use this bulls*** to fuel you.”

Another supporter wrote, “That’s a shame. Arnie seems to love them equally though, if not Joe a little more because he’s walking in his footsteps.”

The conflict between Schwarzenegger’s children was highlighted during the FUBAR premiere. Witnesses said that while the actor’s other children went home, Baena stayed for the after-party at The Grove in Los Angeles, California.

The former California governor, seen at the premiere holding a giant “World’s Best Dad” mug, is reportedly “really close to Joe.” One source said, “I’ve been at several events where he’s brought him along.” The source added, “It’s not fair, but I guess it’s understandable — he’s the product of something that should not have occurred. The Schwarzenegger kids have consistently navigated the situation with respect and class.”

“Arnold loves all of his children. He has a great relationship with all of them.”
