Does Joseph Baena have a relationship with Arnold Schwarzenegger?

Yes, they have an active father-son relationship. The two have been photographed together at the gym and at family events, and Arnold has publicly supported Joseph’s career. Joseph told South China Morning Post that he trains with his father and credits him for his fitness inspiration.

Joseph Baena and Arnold: public appearances and bonding

  • In 2015, Joseph appeared with Arnold at a bodybuilding competition — their first public outing together (HELLO! Magazine).
  • They have been spotted working out at Gold’s Gym in Venice, California.
  • Arnold joined Joseph for a father-son photo shoot in 2020.

How often do they see each other?

According to interviews, Joseph sees Arnold regularly — several times a month. The bond is strongest around fitness, but they also share meals and family gatherings. Arnold has said he’s “proud” of Joseph’s drive.

Arnold’s public statements about Joseph

Joseph is a great kid. I regret the affair and the pain it caused, but I’m grateful for the relationship we have now.Arnold Schwarzenegger

Arnold’s regret is well-documented. In the Netflix documentary Arnold, he discussed the affair and the secret child, acknowledging the hurt it caused his family (EntertainmentNow).

The upshot

Arnold and Joseph have built a genuine bond despite the complicated start. For Joseph, the connection is both a legacy and a weight — he’s often seen as Arnold’s “mini-me,” but he’s working to define his own identity.

When did Joseph Baena find out he was Arnold’s son?

Joseph learned the truth about his paternity around age 13, before the 2011 public scandal. His mother, Mildred Baena, was the one who told him. “I loved him, the indiscretions happened only a few times,” Mildred said in an interview with Entertainment Tonight, explaining that the affair was not a long-term relationship.

Joseph’s childhood and the secret

  • Joseph grew up in Bakersfield, California, raised by his mother (HELLO! Magazine).
  • He attended a Catholic school and later moved to Los Angeles for college.
  • His mother kept the identity of his father private until she felt he was old enough to understand.

How his mother Mildred handled the revelation

Mildred told Joseph about Arnold in a private conversation, emphasizing that his father was a good man who had made a mistake. Joseph has said he was initially shocked but later came to accept it.

Public disclosure in 2011

The news broke in May 2011 when Arnold Schwarzenegger admitted to fathering a child with his housekeeper. The revelation led to his separation from Maria Shriver and dominated tabloids for months. HELLO! Magazine reported that the family was “devastated.”

The paradox

Joseph learned the truth at an age when most kids are navigating middle school, not a national scandal. His mother’s decision to tell him privately may have softened the impact, but the public fallout was unavoidable.

Do Arnold Schwarzenegger’s kids accept Joseph Baena?

Yes, the half-siblings appear to have accepted Joseph. He has been included in family gatherings, and Patrick Schwarzenegger reportedly invited him to his wedding in 2024 — a strong signal of acceptance (BritainBulletin). Joseph is the younger half-brother of Katherine, Christina, Patrick, and Christopher.

Relations with Patrick and Christina Schwarzenegger

  • Patrick and Joseph have been photographed together at events and workouts.
  • Christina has not made public statements about Joseph, but there are no reports of conflict.
  • Katherine, the eldest, is also said to be cordial.

Inclusion in family events

Joseph attended Patrick’s wedding to Abby Champion in 2024, a major milestone. He also appeared at Arnold’s 75th birthday party, mingling with the extended family.

Public statements from the siblings

We’re a family. It’s complicated, but we’re all figuring it out.Patrick Schwarzenegger

Patrick has not given a detailed interview about Joseph, but his actions — the wedding invitation — speak louder than words.

What to watch

The siblings’ acceptance isn’t just about Joseph; it’s about how the Schwarzenegger family manages public reconciliation. For Joseph, being included is a form of legitimacy that money or fame can’t buy.

Does Maria Shriver get along with Joseph Baena?

Maria Shriver was deeply hurt by the affair and the secret child. She divorced Arnold in 2011 after 25 years of marriage. Over time, reports indicate a polite but distant relationship with Joseph. Joseph has publicly expressed respect for Maria, saying he understands her pain.

Maria Shriver’s initial reaction to the affair

Maria was blindsided. She moved out of the family home and filed for divorce shortly after the news broke. The affair with Mildred, who had been a trusted employee, added to the betrayal.

Current relationship status

Joseph and Maria are not close, but they are not enemies. They have been in the same room at family events without incident. Joseph has stated that he has “nothing but respect” for Maria.

Joseph’s respect for Maria

I understand that it’s a difficult situation. I have nothing but respect for her and the way she handled everything.Joseph Baena

Joseph’s mature attitude has helped maintain a fragile peace within the family.

The trade-off

Maria Shriver gained her freedom and a public voice, but lost the family unit she had built. Joseph gained a father, but at the cost of being linked to a painful chapter for Maria and her children.

Why did Arnold sleep with Mildred Baena?

The affair began while Mildred worked as a housekeeper for the Schwarzenegger family. It was brief, not a years-long relationship, according to Mildred. She told Entertainment Tonight: “I loved him. The indiscretions happened only a few times.”

The affair timeline and background

  • Mildred Baena started working for the Schwarzeneggers in the early 1990s.
  • Joseph was conceived in 1996 and born in 1997.
  • Arnold has said he “did not realize” the affair would lead to a child.

Mildred Baena’s role as housekeeper

Mildred was a trusted employee who lived in the family’s guesthouse. She continued working for the family even after Joseph’s birth, which kept the secret hidden for years.

Consequences for Arnold’s marriage

The revelation ended Arnold’s marriage to Maria Shriver. He has since expressed regret multiple times, both publicly and privately. In his memoir Total Recall, he called it his “biggest regret.”

The catch

The affair was a betrayal of trust that shattered a family. But it also produced Joseph, a young man who has handled the aftermath with surprising grace. The irony is not lost on those who follow the story.
