Alicia Vikander and Michael Fassbender will be playing the role of a couple in the upcoming movie “The Light Between Oceans.” However, the co-stars also happen to be dating each other in real life.

While speaking with Entertainment Weekly, Vikander said that she and Fassbender have an unspoken agreement to keep certain things about themselves and their relationship private. “And I think we’ve made a clear statement that we keep certain things just between us. It was very easy to unite, but that’s quite personal.” Fassbender added the he doesn’t like talking about his personal life and relationships especially with strangers because there’s really no need to do so.

Meanwhile, this does not mean though that Fassbender was never interested to know things about his favorite actors. The actor clarified that he was only curious about the lives of his favorite actors when he was growing up. “That’s human nature. We’re all curious about a lot of things. But my curiosity doesn’t obligate them to tell me,” he said. Vikander, on the other hand, said that she wants some things about her favorite celebrities to stay private. “I love the mystery behind it all,” she said.

In other news, Fassbender, 39, and Vikander, 27, first crossed paths when they filmed the 2014 movie that was directed by Derek Cianfrance, according to People. It was only in January of this year that they came out to the public as a couple at the Golden Globes.

While at the event, Fassbender told Entertainment Tonight that Vikander was flying back to Vegas after the awards show, and he will return to London. “But hopefully we’ll get a minute together. That would be nice. We’ll have a few drinks and then we’re both out of here early in the morning – two in the morning or something,” he said.

“The Light Between Oceans” is slated for release in theaters in the United States on Sept. 2.
