Mildred Baena: Arnold Schwarzenegger Mistress and Baby Mama (PHOTOS)

, 50, has been identified as the 20 year employee ofand, who is at the center of a scandal that caused the couple's breakup.

The woman conceived a child with Schwarzenegger and gave birth to their son at least a decade ago. His age was first reported to be 10 but newer reports suggest the child could be as old as 14.

Mildred kept her secret through the years, while reportedly receiving $1,200 a week as a housekeeper. She was given a severance package in January, within days of Shriver's decision to move out of the couple's Brentwood home.

Baena now lives in a 4-bedroom house with a pool, located several hours outside of LA, with her son and three other children.

The former governor confirmed the news earlier this week, admitting that he did father a child. It appears that his mistress was pregnant at the same time his wife was also pregnant with the high profile couple's youngest son. Arnold said: "I understand and deserve the feelings of anger and disappointment among my friends and family."

Arnold and Marie have four children together: Katherine, 21, Christina, 19, Patrick, 17, and Christopher, 13 -- family photo here.

Baena's My Space page contained several photos of herself with the boy, who bears a striking resemblance to his biological father. We have obscured his face to protect his identify.
