Wind, rain, sudden autumn, cold weather–nothing kept people away from Andrea Bocelli’s big Central Park concert last night. But in the confusion of seating celebs, Ivana Trump and a pal were put in the front row. Imagine the surprise of Donald Trump and latest wife, Melania. Those seats were meant for them! Two more chairs were rustled up immediately, and the foursome now sat together. The tension could be cut with an 18 karat gold knife. Also in the celeb section right up front, Alec Baldwin with yoga instructor gf Hilaria, Katie Couric with youngish boyfriend Brooks Perlin, comic Caroline Rhea, and Sting with buddy Richard Sachs and singer Lisa Fisher. On stage, Bocelli was joined by guest artists Tony Bennett, Celine Dion, David Foster, and Chris Botti. Out in the VIP tent we were startled to see Kim Kardashian and Kris Humphries–they are real, after all, and kind of a mismatched looking couple. They must not have known what Bocelli did, because they split at the intermission. It’s opera, you know. Barilla pasta catered the VIP tent and got an onstage plug from Bocelli. After the show, I was told The Donald has some kind of party. We treated to Neary’s on East 57th St. where some of the Elaine’s crowd has migrated recently. The steaks are to die for, and not expensive. Plus Duffy is there from Elaine’s and he’s brought his Steely Dan CDs. What more can you ask for?
