Photos of Mildred Baena Arnold Schwarzenegger's Housekeeper Lover

The mother -- Mildred Patricia Baena (she goes by Patty) -- was a housekeeper/assistant for the family for more than 20 years. Her jobs included cleaning, laundry, cooking and other chores.

We're told when she became pregnant, she didn't tell Arnold he was the father. Arnold didn't learn he was the daddy until the boy was a toddler.

Patty -- who made $1,200 a week -- was treated well by Arnold once he found out. Sources say Arnold was always "generous." Patty -- who has recently retired -- now lives in a 4 bedroom house with a pool, several hours outside of L.A. with the boy and her 3 other kids.www.mannamart.com
