William P. Lauder

The grandson of Estée herself, 60-year-old William P. Lauder is the businessman and executive chairman of his family's sprawling cosmetics empire, boasting a net worth of around $4 billion. He's the son of philanthropist Leonard Lauder, and the cousin of beloved lifestyle guru and fellow Lauder heiress, Aerin. 

As the story goes, he met his mistress at a party at his own Aspen mansion back in 2000, while he was still married to his ex-wife Karen with whom he has two daughters. The affair started a year later and after one terminated pregnancy in 2005, the couple had a secret love child in 2007.
