Former first daughter Chelsea Clinton wed her longtime boyfriend Saturday in a ceremony that had been shrouded in secrecy but was likely attended by a plethora of famous faces.

Former U.S. president Bill Clinton and his wife, Secretary of State Hillary Rodham Clinton issued a statement about the ceremony, which unfolded behind tight security.

"Today, we watched with great pride and overwhelming emotion as Chelsea and Marc wed in a beautiful ceremony at Astor Courts, surrounded by family and their close friends," the statement said.

"We could not have asked for a more perfect day to celebrate the beginning of their life together, and we are so happy to welcome Marc into our family. On behalf of the newlyweds, we want to give special thanks to the people of Rhinebeck for welcoming us and to everyone for their well-wishes on this special day."

It is believed that hundreds of guests attended the event, at the grand Astor Courts estate.

Roads were closed throughout the surrounding small town of Rhinebeck, N.Y., shortly before midnight Friday.

Police, security guards and the Secret Service kept curious onlookers a safe distance from the estate and the Beekman Arms Hotel, where many wedding guests are staying.

Celebrities spotted in the town included actors such as Ted Danson and Mary Steenburgen, movie producer Steve Bing, fashion designer Vera Wang and former secretary of state Madeleine Albright.

The former president himself wowed locals Friday by having lunch at a local restaurant, walking a few blocks of the trip to shake hands with dozens of people who shouted "Congratulations" and "We love you" as he walked by.

The notoriously publicity shy 30-year-old bride has kept many of the details around the ceremony under wraps.

Andrea Alvin said Clinton's wedding planner sent her a bottle of wine from the local Clinton Vineyards winery along with a note apologizing for the inconvenience.

"I think it's great. It's a happy occasion," Alvin said. "It's good publicity for the town. It's just a weekend. What's losing a weekend in the summer?"

Clinton and Mezvinsky were friends as teenagers in Washington, where the groom's parents served in Congress, and both attended Stanford University. They now live in New York City, where Mezvinsky works at hedge fund G3 Capital. Clinton recently completed her master's degree in public health at Columbia University's Mailman School of Public Health.
