5. Arnold Schwarzenegger
Arnold Schwarzenegger’s wife of 25 years, Maria Shriver, had long suspected that the son of their nanny, Mildren Baena, was fathered by the former California governor. In 2011, the former news anchor confronted the nanny and was able to confirm her suspicions.
Baena was the nanny of Schwarzenegger and Shriver’s four children when she had an affair with the actor. In 1997, both Baena and Shriver were pregnant with Schwarzenegger’s sons, who were born only a few days apart. Baena and Schwarzenegger’s son Joseph was 13 years old when the truth about their relationship was discovered.
