NEW YORK (CBS) — Since the announcement, Chelsea Clinton’s wedding has been one big secret, but now CBS 2 HD has learned the details.

The guest list will include everyone from the Obamas to Oprah, and the menu will be kosher.

The groom is long time boyfriend Marc Mezvinsky.

And the place? Astor Courts in the swank Dutchess County hamlet of Rhinebeck. It’s the former estate of gilded age titan, John Jacob Astor.

“This will be about as secure as the White House for about six hours,” said Jim Langan, Hudson Valley News executive editor, of the venue.

The wedding bells will be ringing July 31.
