The actors met on the set of Crazy, Stupid, Love. and are currently starring together in the new crime drama Gangster Squad.
Talking to MTV News, Gosling revealed that he and Stone share a similar sense of humour and therefore find it difficult to act together in more intense scenes.
"Emma Stone, who I've worked with before, we get a little goofy around each other," he explained. "So it was hard for us to be dramatic."
Gosling also commented on their characters' romantic relationship in the film, saying: "They're putting themselves into such a dangerous situation. There's something between them that's worth that."
Stone recently said that she loved working with Gosling on Gangster Squad as they get along really well.
