The 22-year-old son of Arnold Schwarzenegger, Joseph Baena, recently shared photos of his mom that have never been seen before. Baena is the son of former California Governor Arnold Schwarzenegger and his former housekeeper, Mildred Baena. Their secret affair came to light in 2011 when the news broke that the Terminator actor had sired a son with his family's long-serving housekeeper Mildred.

The news brought to an end Arnold's 25-year-old marriage to Maria Shriver. The renowned bodybuilder and Maria have four kids: Katherine, 30, Christina, 28, Patrick, 26, and Christopher, 22 who was born the same week as Mildred's son Joseph. Mildred had worked as a housekeeper in Arnold's home for 20 years and she retired in early 2011 the same year that her relationship with Arnold came to light. After the 2011 scandal, Arnold tried his best to create a good relationship with Joseph, and ever since, they have been close.
