It seems that Arnold Schwarzenegger had a hard time telling his then-wife, Maria Shriver, about the secret son he had with the family's former nanny, Mildred Baena.
According to The Sun, Schwarzenegger revealed how the bombshell news came out that Joseph Baena, now 25, was his son. The Sun reports that the "Terminator" star shares the story in the upcoming Netflix documentary, "Arnold."
The former couple had started couples therapy and one day, the therapist told her, "Today, Maria wants to be very specific about something," Schwarzenegger reportedly says. "She wants to know if you are Joseph's father."
"I thought my heart stopped. And then I told the truth. 'Yes, Mary. Joseph is my son,'" he then adds. "She was obviously very hurt by it."
Arnold and Maria were married in 1986 and are the parents of four children. The betrayal with Mildred Baena happened in 1996.

Schwarzenegger said he and Mildred believed she was pregnant by her husband, but he began to doubt it as Joseph grew older.
"At first I really didn't know, but the older he got, the more it became clear to me," Schwarzenegger said.
Arnold Schwarzenegger and Maria Shriver officially finalized their divorce in 2021.
