Joseph Baena: Arnold Schwarzenegger’s Son on His Own Terms

Few people grow up learning that their father is a Hollywood legend—and even fewer choose to carve a path entirely separate from that legacy. Joseph Baena, the son of Arnold Schwarzenegger and Mildred Baena, has done exactly that: building a career in acting, fitness modeling, and real estate under his mother’s surname. Here’s a complete look at his life, the family secrets that shaped him, and why he refuses to lean on his father’s fame.

Born: October 2, 1997 ·
Mother: Mildred Patricia Baena ·

Notable Achievement: First place in NPC Natural Colorado State, 2026

Six key facts, one pattern: Joseph Baena’s public identity is built on his own achievements, not his father’s shadow.

When did Arnold find out Joseph Baena was his son?

Arnold Schwarzenegger learned that Joseph was his biological son in 2011, after Mildred Baena—who had worked as the family’s housekeeper for years—shared the truth. Joseph was about 14 years old at the time. According to the Los Angeles Times, the news became public knowledge by 2012.

The pattern: a secret that upended two families, yet led to an unexpected father-son relationship.

What was the timeline of Arnold’s discovery?

• Early 2011: Mildred Baena tells Arnold he is Joseph’s father.
• Arnold confirms paternity through a DNA test.
• He then informs Maria Shriver during a phone call.
• Public announcement follows in mid-2011.

The Independent reports that Arnold later said in his Netflix docuseries Arnold, “Yes Maria, Joseph is my son.” The implication: the discovery reshaped two families overnight, but Arnold has since worked to build a bond with Joseph.

Did Joseph Baena know Arnold was his dad?

Joseph has said that his mother told him the truth about his father when he was young, but the information stayed private for years. According to LADbible, Joseph stated he “never really had the Schwarzenegger name in general.” He met Arnold in person as a teenager and began building a relationship that now includes regular workouts together.

How did Joseph learn the truth about his father?

• Mildred Baena told Joseph at an early age.
• Joseph kept the secret through his childhood.
• First in-person meeting with Arnold happened after 2011.

What is Joseph’s relationship with Arnold today?

Today the two are close. They are often photographed working out together, and Arnold has praised Joseph’s independence. Fox News quoted Joseph saying, “I don’t believe in handouts.” The pattern: a father who respects his son’s drive to stand alone.

How did Maria find out about Arnold’s love child?

Maria Shriver discovered the affair in 2011 through a phone call from Arnold himself. According to The Independent, she was deeply hurt and separated from Arnold soon after. The marriage eventually ended in divorce.

What was Maria Shriver’s immediate reaction?

Maria reportedly felt betrayed and devastated. In her memoir, she wrote about the pain but also the journey toward forgiveness. Publicly, she has not disparaged Joseph and has even been photographed with him at family events.

How much did Arnold pay Mildred Baena?

Arnold reportedly paid Mildred a financial settlement, though the exact amount has never been confirmed. Los Angeles Times noted the settlement was private, adding to the lingering uncertainty around the affair’s financial resolution. Why this matters: the silence around the sum keeps one of Hollywood’s most personal stories partially untold.

Why doesn’t Arnold Schwarzenegger’s son Joseph have his last name?

Joseph Baena has consistently said he wants to build his own identity. In a HOLA! USA interview, he explained: “I don’t want to ride on the coattails of my famous father.” He also stated he “wants to make his own name in Hollywood.” Arnold has publicly supported the decision, calling Joseph “very smart” for doing so.

What is Joseph’s own reasoning for keeping the Baena surname?

• He was raised with the Baena name and feels it’s his.
• He doesn’t want to be handed opportunities because of his father.
• He sometimes uses “Schwarzenegger” informally, but legally remains Baena.

How does Maria Shriver feel about Joseph Baena?

Maria Shriver has publicly expressed forgiveness toward Arnold in her memoir and has been photographed with Joseph at gatherings. Fox News reported that Joseph speaks warmly of Maria, calling her a supportive figure. Their relationship appears positive today, though the initial betrayal was painful.

Did Maria Shriver ever forgive Arnold?

Yes. In her memoir, Maria wrote that forgiveness was a process but she reached it. Arnold has also expressed regret and gratitude for her grace.

What is the current relationship between Maria and Joseph?

They have attended family celebrations together, suggesting a cordial bond. Joseph has not publicly shared many details, but the photos speak to acceptance.
