Sharon Stone has sworn off marriage and is happy being a single mother to her three young boys. The CASINO star's first marriage to producer MICHAEL GREENBERG ended in 1987, and she was married to Phil Bronstein from 1998 to 2003. She explains, "I'm not big on marriage. But when I married before, the people I married were very big into marriage, supposedly. "When I do something, I do it with a lot of determination. In the modern world, a lot of people get married like shampoo and a cream rinse. "Like, 'Let's get married and let's get divorced.' And I can't relate to that."
