Emma Stone and Ryan Gosling strolled through the East Village Saturday evening after buying frozen yogurt at 16 Handles on Second Avenue. “They were walking together with yogurt in their hand,” a witness said. “They were both smiling and laughing. It was very friendly. A lot of people were looking at them.” A source close to Stone, recently linked to her “Spider-Man” co-star Andrew Garfield, insisted she’s “just friends” with Gosling, her “Crazy, Stupid, Love” co-star. Stone’s rep declined to comment. Gosling’s rep didn’t get back to us.
