Karina Smirnoff MLOPEZKARINA042207_01.jpgNo longer able to hide it, Mario and Karina looked very much in love as they held hands and smiled at each other on their way to dinner at Katana on Friday night! They were even talking wedding registries...Ok, it was good friend Eva Longoria's wedding registry they were talking about, but still. We asked the formerly closeted couple if they were "officially dating" and Mario just pointed out the fact that they were holding hands and said "what do you think?" Karina also talked about her work on DWTS and her new partner, and Mario made a prediction on who would win this season...Karina & Billy Ray, of course!
