It has been a rough week for Arnold Schwarzenegger and his family, but the ex-governor of California still managed to stay calm under pressure as he left his Brentwood office Tuesday.

It was revealed Tuesday the Terminator star fathered a child about ten years ago with a former member of his household staff.

Mildred Patricia Baena was said to have "pursued" the actor while working for the family, and bragged about having unprotected sex at the home during the day while the family was out.

Schwarzenegger reportedly wasn't told about his son until the boy was a toddler, and he managed to keep the whole thing under wraps until now.

The actor said in a statement: "After leaving the governor's office I told my wife about this event, which occurred over a decade ago. There are no excuses and I take full responsibility for the hurt I have caused. I have apologized to Maria, my children and my family."
