Schwarzenegger admitted fathering a child with a household staffer. The Los Angeles Times reports that Arnold Schwarzenegger admitted what happened to wife Maria Shriver after he left the governor's office. The child was
born more than 10 years ago.

Sorry, XL Country.  It's the second story about cheating I have had in as many days.  What do you think?  Is cheating more common than staying faithful?
