A Secret Revealed
Joseph Baena, Arnold Schwarzenegger’s son from an affair with housekeeper Mildred Baena, was a secret for years. In 2011, the truth surfaced when Schwarzenegger admitted in therapy, “Maria wanted to ask about a child—whether you fathered a child with your housekeeper Mildred.” This confession ended his 25-year marriage to Maria Shriver.

Distant Half-Siblings
Despite Arnold’s close bond with Joseph, his four half-siblings—Katherine, Christina, Patrick, and Christopher—keep their distance. Joseph was absent from Katherine’s 2019 wedding, sparking speculation. While he congratulated her online, fans questioned his exclusion, calling it “heartbreaking.”

Minimal Interaction
Joseph follows some half-siblings on social media, but they don’t follow back. On National Siblings Day, Katherine shared a tribute that excluded him. A source revealed, “Katherine and Christina have no relationship with Joseph,” though Patrick and Christopher occasionally connect. In 2021, Patrick and Joseph were spotted working out together.

Joseph’s Success & Arnold’s Support
Despite the family divide, Arnold supports Joseph. On his birthday, he wrote, “I am so proud of you!” Joseph, now a fitness model and actor, embraces his journey with his father’s encouragement.
