Famous wife Barbara Sinatra has a net worth of $100 million. If you're surprised by that net worth, remember that Barbara Sinatra was the wife of none other than Frank Sinatra before his death in 1998. Her career began, however, as a showgirl and model. Born in Missouri, she met her first husband, Robert Harrison Oliver, an executive affiliated with the Miss Universe pageant. After the birth of her son Bobby, the couple divorced, whereupon she started a career in show business as a showgirl in a Las Vegas casino. Also during her "showgirl period," she worked as a fashion model for the famous Mr. Blackwell.
After divorcing Oliver, she married the "fourth Marx brother," Zeppo Marx, in 1959. In a somewhat unusual development, her son Bobby actually changed his name to "Bobby Marx" when this marriage took place. Like her first marriage, her marriage to Zeppo ended in divorce, after which she began seeing the legendary Frank Sinatra in the 1970s. This marriage was the one that stuck, since they stayed together until his death in 1998. During this union, they started the Barbara Sinatra Children's Center, providing rehabilitative therapy to victims of sexual abuse. At 84 years young, Barbara Sinatra is one of the few living connections to an American icon.
