Mother of Arnold's Love Child Revealed on Newsfeed -Mildred Patricia Baena from Guatemala you’re the next contestant on who wants to mother the son of a millionaire! If you’re not familiar with who Mildred Patricia Baena is, she’s the mother of the Arnold Schwarzenegger’s love child. Pictures of this mysterious woman with an inordinate amount of plastic surgery (who paid for that?), surfaced along with photos of the boy who looks eerily similar to the experiment Cyberdine Systems ran on humans to become terminators. Coincidence I think not. Maria Shriver couldn’t be reached for comment, but when we asked her friends they said, “she will not be back.”Arnold's mistress is finally found.
