Chelsea Clinton’s hush-hush wedding may as well be classified, but one thing is no secret: There will be tears.


The only child of former President Bill Clinton and Secretary of State Hillary Clinton will marry longtime boyfriend Marc Mezvinsky this month in a ceremony that has withstood leaks better than many secrets in Washington.


“You should assume that if he makes it down the aisle in one piece it’s a major accomplishment,” Hillary Clinton said of her husband in comments from Pakistan yesterday.


Local media have reported that the wedding will take place on July 31 at an estate in Rhinebeck (north of New York City) and there is speculation that the bride will wear Oscar de la Renta.


“My lips are sealed,” Hillary Clinton said. “I am under very strict orders not to talk about it.”

The guest list — rumored by New York media to include around 400 people — is among the closely guarded secrets. Hillary Clinton has a message for all those Clinton supporters who might be still hoping for an invite: “We love you all but this is her wedding.”
