Mario Testino will be honored at this year’s El Museo del Barrio Gala, and Kate Winslet is scheduled to present the Peruvian top fashion photographer with a silver Asprey tray inscribed with the names of 30 of his closest friends at the event. The host of names includes Tom Ford, Claudia Schiffer, Demi Moore, Elizabeth Hurley, Blake Lively, Julia Roberts and Charlize Theron. The black-tie event — chaired by Yaz and Valentin-Hernandez, with Alex Gonzales and Raul Martinez — is expected to draw an elite fashion and social crowd and will be held at Cipriani 42nd Street on May 26.
