While the Obamas were invited (but declined the invitation), Barbra Streisand, Steven Spielberg and Oprah are just a few of the A-listers invited to the July 31st wedding of Chelsea Clinton and Marc Mezvinsky according to People.com. Rumours have the celebration happening in Rhinebeck, N.Y. at a century-old, 13,000-square-foot Beaux Arts pavilion called Astor Courts. The guest list is relatively small — at a mere 400 and includes only those who personally know the bride and groom. Other details that have been released include — wedding planner Bryan Rafanelli, artistic director of the Four Seasons George V hotel in Paris will be doing the flowers, and Jimmy Vali, president of Vali Entertainment is in charge of the music. Other speculations include the bride’s gown, which will likely be an Oscar de la Renta frock, according to Extra. The Daily Beast’s Lynnley Browning did some sleuthing of her own and discovered some more details about the big day including the rehearsal dinner, which is being catered by the upscale eatery Terrapin Restaurant, many guests have been booked into the nearby Beekman Arms inn and the wedding favours include Rhinebeck Farmers’ Market paper calendars and orange tote bags with woodcut honeybee prints. So until the weekend passes, we’ll just have to keep speculating.
