Sharon Stone has been friends with Antonio Banderas for decades, and, contrary to reports, the actress is NOT dating the Spanish star, following his recent split with actress Melanie Griffith, his wife of 18 years. The Spanish tabloid “Grazia” claimed Stone, 56, and Banderas, 53, have become “closer than ever” and are “making plans for a getaway together.” Stone responded angrily, saying “Antonio is a brother to me and Melanie has been with me for each and every birth of my three children.
