"Thurmond continued to 'buy' Essie May Washington's silence, which, I assume Schwarzenegger had done the same with the household employee who bore his child," said Alexander.
"Both of these women and ultimately their children understood that the way to get along is to say as little as possible and not have your life made miserable," she said.
Similarly, Prince Albert of Monaco, one of the richest men in the world, is supporting two working-class women who have given birth to his love children.
In 2006, the son of movie starlet Grace Kelly and Prince Rainier, admitted he had a 14-year-old daughter following an affair with California waitress Tamara Rotolo. Today, Jazmin Grace Grimaldi is 19.
Just the year before, he admitted that he had fathered Alexandre Coste, now 11, the daughter of flight attendant Nicole Coste from Togo.
Jesse Jackson, 69, had an affair with a former employee at his Rainbow/PUSH coalition that produced a daughter, Ashley. The once presidential candidate said that he had never offered payment to Karin Stanford, who is now 49.
In 2001, she sought formalized child support and told ABC's 20/20 that she only wanted him "to be a father" to the child, who is now 12. She reportedly received $3,000 a month from Jackson.
"I really need to clear up some misinformation about me," Stanford, now an author and a professor, told the Chicago Tribune in 2001, when she sought child support. "I'm not a blackmailer. I've never received any payoff money…please don't call me a mistress.
Stanford was said to have received a $100,000 annual salary from one of Jackson's organizations. "That implies I'm a kept woman," she told the newspaper. "I am not that."
In 2009, New York gubernatorial candidate Carl Palladino, now 64, confessed a secret child to his wife of 40 years, Cathy, after their son was killed in a car accident. The girl was conceived during an extramarital affair a decade ago with Sue Brady, an ex-staffer in his development company.
Other modern day philanderers include 2008 presidential candidate John Edwards, who now has a 3-year-old daughter Quinn with filmmaker Rielle Hunter. They had an affair while he was on the campaign trail, which later broke apart his own marriage to Elizabeth, who died of breast cancer in 2010.
The victims in all these scenarios are often the children -- not only the love children, but legitimate siblings, according to Dr. Judy Kuriansky, professor of psychology at Columbia's Teacher's College.
"This is very traumatic for the love child," she said. "Basically they are being kept as a secret and sometimes they don't even know who the father is. Nothing is worse than not being recognized or not being accepted by your parents. But we also have to think about the [half] siblings."
Just today, Schwarzenegger's 17-year-old son Patrick Shriver, who uses his mother's name, tweeted these rap lyrics: "Some days you feel like shit, some days you want to quit and just be normal for a bit, yet I love my family till death do us apart."
"This is a way of assuaging his feelings," said Kuriansky. "It's not only the child that's been kept in the dark all this time...It's tremendously distressing have a role model father who does such things."
But Kuriansky said there are other victims, including, perhaps, Schwarzenegger himself.
"It's the whole idea of a shotgun wedding -- getting the guy by getting him pregnant," she said of women who target wealthy celebrities.
"He is a victim like everybody else," said Kuriansky. "The love child's a victim, the mother is, in a way, because people think she's reprehensible because she broke up a marriage. And we are victims, too, because we have been duped. He ran for governor and kept it a secret until he left office."
