The celebrity cheater: The former "Governator" and action hero.
The other woman: Longtime housekeeper Mildred Baena.
What was gained: The worst reviews of Schwarzenegger's career. The world was shocked, not only that the former bodybuilder would have an affair and father a love child with Baena, but also that it would be his wife, Maria Shriver, who recognized the unmistakable resemblance in her housekeeper's son and ended the charade.
Arnold, of course, gained a son, 14-year-old Joseph, who was born just five days after Shriver gave birth to the couple's fourth and youngest child, Christopher, in 1997.
What it cost: Let's call this a redistribution of wealth, shall we? According to Celebrity Net Worth, the Hollywood action hero-turned-governor is worth in the neighborhood of $300 million. Shriver, an Emmy Award-winning television journalist, has amassed around $100 million, also a very nice neighborhood.
According to TMZ, there was no prenup. Because California is a community property state, most of the millions they've accumulated over a quarter-century together could be split 50-50, leaving Shriver with a settlement in the comfortable neighborhood of $200 million.
Baena says Schwarzenegger was "generous" to her following the birth of their secret son.
