Bob Colacello has added a 10,000-word foreword to his Andy Warhol book, “Holy Terror,” and Diane von Furstenberg hosted a bash at her Meatpacking District studio to celebrate.

“So much has happened between 1990 and 2014,” the author told Page Six, citing the spike in the contemporary art market, including Warhol works.

Von Furstenberg plays a central part in the book, as do Truman Capote and designer Halston.

At DVF’s to celebrate were Mercedes Bass, Graydon Carter, Vito Schnabel, Mary-Kate Olsen, models Coco Rocha and Karolina Kurkova, Fran Lebowitz, Joel Grey, and artists Ross Bleckner, Dustin Yellin and Enoc Perez.
