The Clintons have not confirmed Rhinebeck as the wedding location, but the mother of the bride told CBS News Correspondent Elaine Quijano that she's thrilled.
"I'm very excited. I think she is a really responsible young woman," said Secretary of State Hillary Clinton. "Her fiancée is a wonderful young man."
Mayor Jim Reardon believes the Rhinebeck rumor is true.
Asked what he thought his town might look like come July, Reardon said, the thinks "it's going to look like a circus."
The trickle of details leaking out has now turned into a torrent.
The wedding will reportedly take place at the $12 million dollar estate known as Astor Courts - 50 acres encompassing a five-bedroom beaux-arts pavilion - and owned by Clinton donors.
Just two days ago, the local paper, the Hudson Valley News, spotted a newly-erected tent on the grounds of the estate.
"Our sources indicate that it's going to be constructed in such a way that it's going to be all glass on the river side so the guests will be in there, air conditioned, with an unimpeded view of the Hudson," said Jim Langan, the executive editor of the Hudson Valley News
Wedding guests - including A-list celebrities - will reportedly stay at the historic Beekman Amars, where Langan says the owners have signed a confidentiality agreement.
The rehearsal dinner is expected to take place in a stone bar at Grasmere, a 525-acre private estate.
Gift bags will reportedly come from this boutique and will include wine bearing the Clinton name from a local vineyard.
Experts estimate the wedding could cost roughly $2 million - with guests, that's $1,000 a head - for catering alone.
Langan says the wedding plans even call for electricians on standby.
"They have been instructed by the wedding planner that they have to be attired in tuxedos so they blend in," he said. "hey don't want these guys sitting around in farmers jeans while passing the caviar."
Langan also drove CBS News to a purported top-secret location where the Clintons will be staying.
But the mystery of Rhinebeck's real connection to Chelsea Clinton's wedding will finally come to an end in 6 days, still plenty of time for rumors in this small town to run rampant}
