Maria Shriver, Arnold Schwarzenegger, and Mildred Baena
When Arnold Schwarzenegger and Maria Shriver filed for divorce in 2011, the media went wild. Schwarzenegger revealed that during the course of their 25-year marriage, he had fathered a son with the family's housekeeper, Mildred Baena. Baena's son was born only five days before Shriver's second son, meaning that the two women were both pregnant with Schwarzenegger's baby at the same time.
