Well, that was prompt. The mother of the child Arnold Schwarzenegger fathered out of wedlock has been revealed: Mildred Patricia Baena, who goes by Patty Baena.

Baena was a housekeeper/assistant for the family for 20-plus years. Her jobs included cleaning, laundry, cooking and other chores for Arnold and Maria Shriver.

Sources say in the late ’90s Patty began to pursue Schwarzenegger.

She told friends they’d have unprotected sex during the day at the house, where Patty Baena sometimes stayed overnight. No one ever caught them in the act.

When she became pregnant, she didn’t tell Arnold he was the father.

Schwarzenegger Arnold didn’t learn he was the dad until the boy was a toddler, which would have been right around his first run for governor, or possibly after.

Mildred Patricia Baena, who made $1,200/week was treated well by Arnold before, and especially after he found out. Sources say he was “always generous.”

Patty, who has recently retired, now lives in a house several hours outside of L.A. with the boy and three other kids. Arnold and Maria have four of their own.

News of Schwarzenegger’s out of wedlock child broke earlier this week and shed new light on his recent separation from Maria Shriver, his wife of 25 years.

It’s unclear why he told Maria, but the revelation apparently caused her to move out of the family’s mansion abruptly. Given the circumstances, not shocking.

The affair took place over a decade ago, and Patty Baena continued to work for the family until this year, making this way more than your standard affair.

The love child’s name is not being revealed, however his features are like Arnold’s. TMZ released the following picture last night, in addition to this report:
