PRADA, 34, AND O’REILLY, 34

Oct. 4 – Newlyweds Shirley Prada and Edward O’Reilly like it keep it all in the family. When the Manhattan duo tied the knot at the Church of the Resurrection in Rye, the groom’s 80-year-old grandfather served as his best man! “They are best friends and inseperable,” says Prada, who works at J.P. Morgan. “In fact, when Ed’s grandfather remarried last year, Ed was the best man.” In addition to the best man, 250 additional family members and friends joined O’Reilly, the president of Cyber Search Global, and his bride for an autumnal reception at the New York Athletic Club in Pelham Manor
