Designer Dennis Basso, who will wed his partner of 20 years, Michael Cominotto, at The Pierre hotel next month, was treated to a bridal shower by close friends at Le Cirque late last week. Basso was feted at the shower on Thursday by hosts Amy Fine Collins, Somers Farkas and interior designer Joanne de Guardiola. A spy at the 58th Street restaurant told us that couture fur designer Basso “was wearing a crown,” while his well-heeled guests including Nicole Miller, Jamie Tisch, Star Jones and Jamie Gregory donned tiaras and costume jewelry. The group of 25 toasted Basso with Champagne and cake following a long lunch. Sources tell us even though he is launching a bridal range for Kleinfeld, Basso plans to wear a dark suit on his big day, which will be The Pierre’s first same-sex wedding in its 81-year history.
