She's a yummy mummy! Basic Instinct star Sharon Stone, 57, turns heads in strapless dress as she steps out with son Quinn

Her beauty led the writer of Basic Instinct to call her the 'ripest of ripe peaches.'

And Sharon Stone was definitely the vision of a yummy mummy as she stepped out with her son Quinn in Beverly Hills on Wednesday. 

The 57-year-old was looking great for her age as she stretched her legs in the well-heeled area of Los Angeles County.

Silver favourite Sharon showcased her sizzling figure in a patterned strapless maxi dress, which she coupled with casual sandals.

And there were definitely still flashes of the old magic that led Basic Instinct writer Joe Eszterhas to call her 'the greatest American sex symbol since Marilyn Monroe' and the 'ripest of ripe peaches, the apotheosis of the curvy, beauty pageant blond.'

However the self-styled genius showed her maternal side during her outing, holding hands with 10-year-old Quinn as they crossed the street. 

Single Sharon has said her disastrous six-year marriage to former San Francisco Chronicle executive editor Phil Bronstein is one of the reasons she has stayed unmarried since their divorce back in 2004.

The actress said: 'Marriage was kind of a losing proposition for me.' The Agent X star was also wed to MacGyver producer Michael Greenburg from 1984 to 1990.

The two also had a custody battle in 2003 over their adopted son Roan, who is now 16-years-old.

After her split, the Sphere actress adopted Laird, 11, and Quinn on her own.
