Aristotle Onassis' 36-year-old granddaughter Athina was invited to the wedding of Sami Zane and Lauren van Berkel in Monte Carlo reported Greek newspaper Proto Thema. In what was one of her rare public appearances, Athina Onassis was one of more than 700 guests at socialite event of the year. As photos of her at the event would suggest, Athina Onassis is no longer the image of woman-girl, but rather has grown into a mature beautiful woman embracing her femininity. Although a little more modest in her clothing choices than might suit her, she nevertheless exudes a solid charm. The photo was uploaded by Greek-American Gianna Darili to on her instagram account who also attended the lavish wedding with her husband.
