Maria Shrive, 55, is said to have asked her family's housekeeper, Mildred Baena, 50, if her son was fathered by Arnold Schwarzenegger. Baena allegedly broke down and confessed, according to America's Radar Online. Schwarzenegger only came clean after Shriver told him she new the truth about his 13-year secret, insiders say. 

Mildred Baena's son, believed to be Arnold's love child, was born on October 2, 1997. The actor and his wife Maria Shriver welcomed their second son, Christopher, on September 27 that same year. Schwarzenegger and 
Shriver have three other children together: Katherine, 21, Christina, 19,
and Patrick, 17.

It has been claimed that Schwarzenegger did not discover he was the parent until the child was a toddler. While the identity of the boy, now 13, is being protected, observers have noted that his mouth and teeth closely resemble the star.

There is no denying that Arnold, Mildred and son all resemble the Shrek family!! Thoughts?
