The unlikeliest pair ever, Christie Brinkley and His Holiness Gyalwang Drukpa, walked the red carpet the other night at the Waldorf-Astoria, where the Himalayan holy man received a UN Millennium Development Honor for his humanitarian work. Drukpa is the leader of the second-largest Buddhist sect after the Dalai Lama. Tomorrow night, David Schwimmer, Michelle Yeoh and “Gossip Girl” heartthrobs Chace Crawford and Ed Westwick are expected to join His Holiness for a fund-raiser at Asia House.
