Lauren Lawrence hosted a birthday celebration for 82-year-old renowned restaurateur Sirio Maccioni at her home in the Upper East Side of New York City. Honoring Sirio on this special occasion were former fashion designer Carolyne Roehm; supermodel Carmen Dell’Orefice; art patron Iris Cantor; former editor-in-chief of Town & Country Pamela Fiori; David Patrick Columbia from New York Social Diary; interior designers Susan Gutfreund, Geoffrey Bradfield, and Alex Papachristidis; and designers Dennis Basso and Maggie Norris. Also attending the party were A-listers Elizabeth Kabler, Lady Liliana Cavendish, Kalliope Karella Rena, Larry Kaiser, Ann Rapp, Consuelo Vanderbilt Costin, Hormoz Sabet, and Lucia Hwong Gordon, among others. Topping off the guest list was Dina Merrill’s grandson Cole Rumbough, who sang Sirio a tender rendition of “Happy Birthday” before the cake was cut.
