Actress Sharon Stone Stuns In Bikini

Sharon Stone has been showing off her toned body since she stripped down to nothing to seduce Michael Douglas in 1992's Basic Instinct.

And the 58-year-old movie queen is still at it.

On Sunday the mother-of-three put her svelte frame on full display as she posed in a teeny bikini while on the steps of the swimming pool at her Los Angeles mansion for an Instagram post. 'Stay cool,' she wrote in her one of her hashtags.
