But could the numerous leaks about the secret affair are all fake, so the real one can be held in privacy?
As CBS News Correspondent White Johnson reports, local officials and residents are beginning to wonder.
The word's been that the former first daughter will be tying the knot in two weeks on an estate in the historic, picturesque setting 90 miles north of New York City.
"Everybody's been talking about it," says Rhinebeck Mayor James Reardon.
For Reardon, says Johnson, it's "the ultimate stress headache," with Chelsea and fiancé Marc Mezvinsky apparently ready to tie the knot in Rhinebeck July 31.
But, says Reardon, just two weeks out, the village has yet to receive any confirmation. "I know very little," he says.
That, as rumors among Rhinebeck's 4,600 residents run rampant. One told CBS News he hears President Obama and Oprah Winfrey will attend.
And Hudson Valley News Executive Editor Jim Langan insists Rhinebeck will indeed be the locale.
"If this is a ruse or a head-fake, it's worthy of Oliver Stone," Langan observes. "Trust me, it's gonna happen here."
Still, while he says plans are in motion, the uncertainty is difficult for a town with only 14 part-time police officers and three squad cars, Johnson says.
"I just want to address the safety needs of this community and make sure we have plans in place for that," the mayor points out.
Local authorities, state police and the Secret Service will meet early next week to discuss the possible event, Johnson says.
In the meantime, a town accustomed to Clinton sightings may soon have a big one to talk about.
"I think they stop by at least once a summer," one local tells CBS News.
