Is life imitating art, when it comes to Sharon Stone’s sexuality?

The 53-year-old actress, who famously played a bisexual in Basic Instinct, was spotted passionately locking lips with a mystery lady in Los Angeles on Sunday – and Breaking Celebrity News has photos of the steamy smooch!

Showing off her fabulously fit figure in workout gear, the blonde beauty and her lady friend were taking a stroll in the West Hollywood area, before they stopped and embraced and engaged in a little-more-than-friendly kiss on the lips.

In 2008, Stone, who has never come out as being bisexual, was quoted saying: "Everybody is bisexual to an extent. Now men act like women and it's difficult to have a relationship because I like men in that old-fashioned way. I like masculinity and, in truth, only women do that now."
