Arnold Schwarzenegger’s former housekeeper Mildred Patricia Baena is pictured above with her son. TMZ reports that Baena is Schwarzenegger’s former mistress and the boy is his child.

Access Hollywood obtained a copy of the child’s birth certificate, which lists Rogelio Baena as the father of the child – born on October 2, 1997 – just days after Schwarzenegger and Shriver’s youngest son Christopher was born on September 27, 1997. The child, now 13, was born in Burbank, Calif.

According to Baenas’ divorce papers Mildred and Rogelio separated less than a month after the child was born. Despite being named on the child’s birth certificate, they did not list having any minor children together. Mildred filed for divorce on February 13, 2008.
