TMZ has obtained lots of information -- as well as photos -- of the boy Arnold Schwarzenegger fathered out of wedlock -- and he looks shockingly like Arnold himself.
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.
Sources tell TMZ -- in the late '90s Patty began to "pursue Arnold." She told friends they would have unprotected sex during the day at the house. Patty never slept overnight at the house and no one ever caught them in the act.
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.
We are not revealing the identity of the boy, however his features are eerily like Arnold's. We have various pictures of him at various ages (he's now in his early teens) and each picture shows striking similarities, especially the mouth and teeth.
Arnold's Love Child -- The Birth Certificate
TMZ has obtained a copy of the birth certificate of the boy Arnold Schwarzenegger fathered ... and he's not listed as the father on the birth certificate.
As TMZ reported, Mildred "Patty" Baena -- who worked as a housekeeper/assistant for Arnold and Maria -- is the mother. She listed her then-husband, Rogelio Baena as the dad.
Baena used a different last name on the birth certificate -- Pena.
The boy was born on October 2, 1997, which now makes him 13. He was born at Saint Joseph's Hospital in Burbank, CA.
Arnold's Baby Mama Baby Shower
Arnold Schwarzenegger's baby mama had a baby shower before his kid was born, and some of Arnold's staff were front and center.
Apparently Mildred "Patty" Baena knew the sex of the baby because the color scheme at the shower was blue.
Among the 15 guests at Patty's home ... Alicia, a cook who worked for Arnold and Maria. She's wearing gray sweatpants.
Among the gifts for Patty -- who was 8 months pregnant at the time -- a baby stroller.
We're told Arnold and Maria sent lots of gifts for the baby.
The boy -- now a young teen -- looks like the spitting image of Arnold.
Arnold's Love Child -- Nicest Kid You'll Ever Meet
Arnold Schwarzenegger's love child with Mildred Patricia Baena is a studious, athletic, fun-loving, charitable, yes-ma'am-no-ma'am kind of kid -- according to the boy's neighbors.
People who live next door to Patty and her son tell us, the boy "is the type of kid you just want to be around. He is so sweet, funny, and handsome."
But that's not it -- we're also told he is extremely well-mannered and smart, loves sports, and is even involved in door-to-door fund-raising for local charities.
The apple falls far from the tree.
Arnold's Baby Mama -- One Naughty Little Pirate

According to the time stamp on the photos -- the Halloween boozefest went down back in October 1996.
