Tom Cruise has reached the highest level in Scientology, referred to as "clear," and reportedly may perform a wedding ceremony for his friend, Australian heir James Packer. According to Women's Wear Daily, Packer is one of the Church of Scientology's richest benefactors after inheriting $6.5 billion from his father last year. A mystery guest, believed to be Packer, has booked the entire Grand Hotel du Cap-Ferrat and the Hotel du Cap-Eden Roc, presumably for guest of his nuptials, set to take place on Wednesday on France's Cote d'Azur.source
