Ryan Gosling may be on an acting hiatus, but that doesn't mean he's let his guard down. Especially when it comes to his woman, yo.

The 'Drive' star and lady love Eva Mendes were in New York for the premiere of their new movie 'The Place Beyond the Pines' when Gosling had a run-in with a photographer who had recently worked with Mendes.

The NY Post reports that after the man greeted Eva with "hey baby," Ryan got in his face, asking, "Who are you calling 'baby'?"

The Post source said Ryan "flipped out" and that Eva had to intervene "and calm everyone down before it came to fisticuffs." After she stepped in and explained she already knew the dude, Gosling eventually shook the guy's hand and the Gangster Squad didn't need to be called.

The night before, the pair -- who've been together for about a year -- arrived and left separately from a party promoting the film. “I didn’t see Eva and Ryan interact once,” said an attendee.

Even if they don't engage in PDAs, it's good to know that chivalry isn't dead when it comes to giving almost-beatdowns to photographers. Just like Sir Lancelot did.
