Joseph Baena: Arnold Schwarzenegger’s Son from an Affair

Joseph Baena was born from an affair between Arnold Schwarzenegger and his longtime housekeeper, Mildred Baena, which led to the end of Arnold’s 30-year marriage to Maria Shriver. Joseph’s resemblance to Arnold eventually exposed the secret, causing a rift in the family.

While Arnold took responsibility and built a strong bond with Joseph, his half-siblings—especially Katherine and Christina—reportedly distanced themselves. Joseph has expressed a desire for a relationship with them, but efforts have not been fully reciprocated. His brothers, Patrick and Christopher, have kept their interactions with him private.

Joseph, born in 1997, graduated from Pepperdine University with a business degree and works in real estate while also pursuing bodybuilding and acting. Despite the strained family dynamics, he maintains a close relationship with Arnold, who supported his graduation and career. His mother, Mildred, has stayed out of the spotlight, aside from occasional social media appearances with her son.
