Arnold Schwarzenegger recently celebrated his 76th birthday with an intimate backyard gathering surrounded by family. The celebration was attended by his four children with ex-wife Maria Shriver—Katherine, Christina, Patrick, and Christopher—who all came together to mark the occasion. A photo from the party shows the group smiling around a table adorned with a cake and two pies. Katherine, who is currently pregnant, shared sweet throwback images on Instagram, including one from her wedding day and another from her father’s iconic *Terminator* era.

Noticeably absent from the party was Schwarzenegger’s fifth child, Joseph Baena, his son with former housekeeper Mildred Patricia Baena. While Baena didn’t attend the event, he did honor his father on social media with a heartfelt birthday post. Sharing a throwback photo of them hugging, he captioned it: “Wishing the Happiest Birthday to my Dad! You are and will always be ‘Número Uno.’”

Despite the physical absence, Schwarzenegger and Baena share a very close bond. Since Baena’s paternity became public in 2011, Schwarzenegger has made efforts to foster a strong relationship with his son, who has followed in his father’s footsteps as a bodybuilder. The actor has been candid about not realizing Joseph was his child until the boy began to resemble him, a revelation that ultimately contributed to his separation from Shriver.

In past interviews, Schwarzenegger has expressed deep pride and affection for all his children. “It’s wonderful to watch them grow up, wonderful to watch them be successful, to reflect on the early days when you were teaching them things, discipline or sports or things like that,” he shared. His comments reflect the strong relationships he maintains with each of his children, both in public and in private life.

Overall, the birthday celebration served as a touching reminder of Schwarzenegger’s dedication to family, even amid past complexities. The presence of Maria Shriver and their children at the party underscored the continued strength of their family bond. And while Joseph Baena wasn’t there in person, his tribute on social media spoke volumes, making the day a celebration of love, unity, and evolving family dynamics.
