"I think once you're a mum, your whole selection process changes... I think what happens is you prioritise differently and you prioritise yourself differently, because you're responsible for these little lives and you want someone special." Hollywood actress and mother-of-three Sharon Stone explains her single status at 57. She was previously married to TV producer Michael Greenburg in the 1980s and divorced her second husband, publishing editor Phil Bronstein, in 2004.
