RYAN Gosling doesn’t sign paper!

The actor was about to board a flight at JFK when a professional autograph collector ran up, shoved sheets of white paper at him and asked for autographs.

Ryan reportedly said, “What are these? I don’t sign pieces of paper. I sign my autograph on photos! Where are your photos?”

The signature hunter replied, “How did I know you’d be here? I was waiting for other celebs flying today. But tell you what — I’ll download and attach your photos after you sign these.”

Ryan said, “I can’t just sign my name on a white piece of paper!”

The autograph collector snapped back, “But what’s the difference?”

Ryan countered, “The difference is…I’m leaving. BYE!”

Meanwhile, Ryan’s romance with Eva Mendes is said to be on the rocks.

The pair haven’t officially split, but, “there was a realization before Thanksgiving that they took things way too fast and were rushing toward a marriage that neither of them particularly needed,” RadarOnline reports.

“They’ve decided to take a break to reevaluate their romance,” a source said.

Gosling, 33, is the one who is undecided, but “Eva wanted to have his babies.”

Gosling has been laying low because he’s coming off a flop movie, Only God Forgives, but he has big things planned for 2014, including the release of his directorial effort, How to Catch a Monster, costarring Mendes.

“The real question is how Eva is going to figure into Ryan’s plans,” the source noted.
