Just a day after Arnold Schwarzenegger announced he had a secret love child outside of his marriage to Maria Shriver, his mistress and baby mama has been uncovered.

Arnold Schwarzenegger shocked the world and revealed the biggest political scandal in recent history when he announced he had a secret love child for over a decade with a household staffer.

Now we know who it is: The couple's former housekeeper Mildred Patricia Baena.

The 50-year-old woman, who goes by Patty, worked for the couple for 20 years until she left under mysterious circumstances in the last several months. While the official word is that she retired in January, sources say she was canned less than a month ago by Schwarzenegger in a desperate attempt to save his marriage.

"Mildred was furious that the father of her 14-year-old son would callously fire her from her job after decades of loyal service," a close friend told RadarOnline.

Just when you thought this mess couldn't get even more shocking, it does: Maria Shriver and Patty were pregnant at the same time. Maria's youngest son, Christopher, was born in September 1997; Arnold and Patty's mystery son is now 14 and born in the same year.

Schwarzenegger has been avoiding the press since his announcement, but Maria held her head up high at the taping of Oprah's last show in Chicago last night after making her own statement about her heartbreak.
