Chelsea Clinton Marries Marc Mezvinsky

Break out the champagne! Chelsea Clinton is a married woman.

Surrounded by 400 friends, and her parents Bill and Hillary (who wore Oscar de la Renta), the former first daughter, 30, wed her longtime boyfriend Marc Mezvinsky, 32, in Rhinebeck, N.Y., Saturday. She wore a dress designed by Vera Wang, a family friend, who was also in attendance.

Shortly after the ceremony, President Clinton and Secretary Clinton released a statement. "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. 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."

The guest list was relatively free of star wattage (without Oprah or Obama) but included Mary Steenburgen, former secretary of state Madeleine Albright, actor Ted Danson, film producer Steven Bing, and a handful of congressmen and other prominent Democrats. According to The New York Times, the interfaith ceremony was conducted by Rabbi James Ponet and Reverend William Shillady. (Chelsea is Methodist; Marc is Jewish).

On Friday, a swarm of paparazzi descended upon Rhinebeck, a small town in upstate New York, trying to catch a glimpse of the festivities. Hillary Clinton wowed crowds outside the rehearsal dinner Friday night, but everybody wanted to see how the teenager who grew up in the White House had blossomed into a blushing bride.

Danson, who attended with wife Steenburgen, told PEOPLE, "We want to wish them the best," adding of the couple, "they are great kids, very family-oriented."

Clinton and Mezvinky, an investment banker who has kept a private life, have been pals since they met at a conference in 1993, and they remained close at Stanford University. But only in 2005 did their friendship turn romantic, when they debuted as a couple at the opening of Tao nightclub in Las Vegas.

They have lived together in recent years in a downtown New York apartment, along with their Yorkshire terrier Soren. As for kids, "I'm not going to put any pressure on her," Hillary told PEOPLE in 2007. "But my friends are starting to have grandchildren and it's a great experience, so I look forward to it someday."
