Inside Chelsea Clinton's Wedding Weekend

Chelsea Clinton will say "I Do" to her boyfriend of about five years, Marc Mezvinsky on today evening in Rhinebeck, New York. What is said to be the wedding of the year, secrecy and buzz has caused hundreds to crowd into this small village hoping to catch of a glimpse of a former president, a secretary of state or their daughter. The 30-year-old daughter of Bill Clinton and Hillary Rodham Clinton is expected to wed her beau at a ceremony at Astor Courts, the ultra-private Hudson riverfront estate, in front of 400 to 500 guests.
The couple were friends as teenagers in Washington, and both attended Stanford University. They now live in New York, where Mezvinsky works at G3 Capital, a Manhattan hedge fund. Mezvinsky worked previously at Goldman Sachs as an investment banker.

Clinton completed her master's degree in public health earlier this year at the Mailman School of Public Health at Columbia University.

Mezvinsky is a son of former U.S. Reps. Marjorie Margolies-Mezvinsky of Pennsylvania and Ed Mezvinsky of Iowa, longtime friends of the Clintons. His parents are divorced.

Meanwhile, a longtime Clinton family friend denied that the wedding would cost more than $1 million. The friend, who spoke on condition of anonymity in keeping with the family's desire for privacy, said the cost will not exceed six figures. Wedding experts told The Associated Press the wedding could cost $2 million to $3 million, while other outlets said it could hit $5 million.

Several other of the 500 attendees will have a low-key arrival via bus. They'll be picked up from local inns Saturday afternoon to be whisked away to the mansion, which is set back from the road with a long driveway protected by off-duty police officers.
