Wearing a green ballgown and patent leather belt from designer Catherine Martin and plenty of diamonds, Google cupcake princess Marissa Mayer mingled with the local society set at the San Francisco Symphony opening night gala. But the big news isn't that Martin clearly chose the green print from the upholstery section at the fabric store, but that Mayer's venture capitalist boytoy Zack Bogue was nowhere to be seen in any pictures. Could the pair be on the outs? Of course, where Mayer goes, A-list Google gay Orkut Büyükkökten and his partner Derek Holbrook are sure to follow. The pair wore white and silver tuxes, respectively — however, with no right hands visible in their photo, we can't tell if the betrothed couple have officially tied the knot yet. Update: Hello, Mr. and Mrs. Don Draper, the Chronicle has pics of Bogue and Mayer arm-in-arm. Looks like Bogue took our advice and dressed it up with a pocket square.(Photo by Drew Altizer via SFLuxe)
