This will probably only make Ryan Gosling's legion of fans swoon even more: The New York Post reports he nearly got into a fight with a photographer Friday because the man dared call his girlfriend "baby." Gosling and Eva Mendes were in New York for the premiere of their new movie, The Place Beyond the Pines, when the fashion photographer—who recently shot Mendes—called out, "Hey, baby!" Gosling "completely flipped out, and it got heated," an onlooker tells the Post. "Ryan got in the guy's face and said, ‘Who are you calling baby?’" Fortunately, Mendes was able to intervene before it came to blows, and the two men shook hands.
