Lesser-Known Hollywood Siblings

23 of 50

Kelly Stone

Famous sibling: Sharon Stone

Though not as famous as her sister, Kelly's work has touched far more lives than "Basic Instinct." As co-founder (with Sharon) of a non-profit charity called Planet Hope, Kelly helps bring hope to homeless and abused children, as well as to their families. —XFINITY Entertainment Staff (Photo by Alberto E.
