Arnold Schwarzenegger Writes Explosive Tell-All About Secret Son

Actor Arnold Schwarzenegger is opening up in a new explosive tell-all book called “Total Recall,” detailing how wife Maria Shriver confronted him over his secret son with housekeeper Mildred Baena.

Maria waited until the day after Arnold left his post as California governor in January 2011 to ask him about the affair in couple's therapy. He writes, “The minute we sat down, the therapist turned to me and said, 'Maria wanted to come here today and to ask about a child — whether you fathered a child with your housekeeper Mildred.”

“I told the therapist, 'It's true,' ” Schwarzenegger answers in the memoir.

According to the Daily Mail, Arnold later delves into the fling he shared with Mildred. The pair had sex in 1996 in the guesthouse of his Pacific Palisades estate while Maria and the kids were on vacation. The actor was filming “Batman & Robin” at the time.

When Joseph was born, Baena put her husband's name on the birth certificate. Arnold “wanted” to believe that was the truth. The 65-year-old kept the housekeeper on staff to help “control the situation,” but Maria eventually saw the resemblance and confronted him several years ago. He denied it at the time.

Once the truth was out, the “Robocop” star admitted to the “screwup” and tried to salvage the relationship by groveling and trying to convince her that she still turned him on. He knows now that he should have revealed the secret years ago.

Arnold says, “But instead of doing the right thing, I'd just put the truth in a mental compartment and locked it up where I didn't deal with it every day.”

The former Governor gave several reasons why he wanted to keep the story under wraps, including not wanting to tell Maria, 56, and her famous family -- the Kennedys.
