The secret is out.  Yet another fairy-tale marriage is about to end after an admission of infidelity.

One of the most powerful marriages in the U.S. is on the brink after Arnold Schwarzenegger revealed that he fathered a child with one of his wife’s long-employed household servants.  Shriver was present at the Oprah Winfrey show when the host was filming the finale.  Shriver was invited on stage with Winfrey’s friend, Gayle King.  Maria Shriver, who has been a longtime friend of Winfrey, told the talk show host that her show had given her, “love, support, wisdom and, most of all, the truth.”

The 63 year old Schwarzenegger, former bodybuilder and former California Governor, apparently told his wife, now 55, about the child soon after stepping down from his post as Governor in January.  The child, now older than ten, was born to a mother who worked for the power couple for more than a decade as a housekeeper.

Last week, the couple announced that they have decided to separate after 25 years of marriage.  Shriver told the media that the decision was heartbreaking and that she was concerned for the children involved.  She asked for media privacy as well as they work to rebuild their lives.  Media privacy may be impossible with these two celebrities, however.
