Details continue to unravel ever since actor and former California governor Arnold Schwarzenegger revealed that he fathered a love child with a former household staff member yesterday.

The staffer has reportedly been identified as Mildred Patricia "Patty" Baena, a housekeeper and assistant who worked for Schwarzenegger and his wife, Maria Shriver, for 20 years before resigning in January. The exact identity of the child still remains under wraps, but new details emerged when TMZ got their hands on a copy of his birth certificate.

The certificate, which blacks out the boy's first and middle name, reveals that he was born on October 2, 1997 just five days after Schwarzenegger and Shriver welcomed their fourth child, Christopher Sargent Shriver Schwarzenegger, to the family. Which means his mistress and his wife were both pregnant at the exact same time with his children.
