Who's invited? The event's elite guest list has been a better-kept secret than the locale — so far, anyway. But we do know at least one couple who won’t be attending: Al and Tipper Gore. The New York Daily News’ Frank DiGiacomo reports today that the recently separated Gores will be giving the nuptials a pass. "The Gores are not attending the wedding," Gore spokeswoman Kalee Kreider said in a statement. "They both wish Chelsea well, believe she is a wonderful young woman, and they share in the family's excitement."
