The news broke on Thursday that former First Daughter Chelsea Clinton will tie the knot with fiance Marc Mezvinsky in upstate New York on July 31. The guest list will likely be massive and include dignitaries and celebrities, but you can count two ol' friends out: Al and Tipper Gore.

"The Gores are not attending the wedding," family spokeswoman Kalee Kreider told the New York Daily News. "They both wish Chelsea well, believe she is a wonderful young woman, and they share in the family's excitement."
