Chelsea Clinton and her fiance, Marc Mezvinsky, are to be married Saturday at the Grasmere Estate in Rhinebeck, N.Y.
The couple held a rehearsal dinner in Rhineback Friday amid heavy security, the New York Daily News said. The Secret Service and state police provided security, roads were closed and a no-fly zone was established, the newspaper said.
Few details about the wedding have been made public, other than that about 500 guests, including TV talk show icon Oprah Winfrey, are expected to attend.
State police said they will patrol the area Saturday to chase paparazzi away.
