It will be a three-day wedding celebration in September for billionaire George Soros and Tamiko Bolton. We’re told the revelry will start with a private dinner at the Museum of Modern Art. The following day, about 900 guests have been invited to a lavish ceremony at the Caramoor Center for Music and the Arts, the Westchester County complex famed for its Italian Renaissance-inspired buildings and lush gardens. If this isn’t enough, the day after that, there will be a smaller luncheon for about 100 close friends and family of 82-year-old George and Bolton, 41. A source tells us the couple have had beautiful felt-bound invitations printed, with different pages devoted to each lavish event.
