Michael Fassbender and Alicia Vikander have made their love red carpet official.

The notoriously private couple walked the red carpet together on Thursday at the Venice Film Festival, in support of their drama, The Light Between Oceans. The two have been dating since December 2014, when they began working together on the tear-jerking film.

Fassbender, 39, kept his arm around Vikander, 27, who looked gorgeous in a plunging floral Louis Vuitton dress. The X-Men: Apocalypse star also looked sharp in a plaid blue suit.

Earlier in the day, the two looked equally stunning at a photocall for the movie, where Fassbender only had eyes for Vikander. The Oscar-winning actress looked lovely in a striped Prabal Gurung dress.

ET sat down with the pair in July, when they admitted they had instant chemistry the night they first met.

"We had met at Toronto Film Festival and just on the dance floor," Vikander revealed, with Fassbender recalling: "I thought [I was a good dancer] until she started dancing and then I felt like I had two left feet."

The duo later "properly" met during rehearsals for The Light Between Oceans, but their chemistry, Fassbender said, "was sort of there from the beginning."

Fassbender and Vikander also sweetly supported one another during awards season earlier this year, when the Swedish actress won an Oscar for Best Supporting Actress for her role in The Danish Girl. Although Vikander didn't publicly thank her beau during her acceptance speech, she did give him a sweet kiss on the lips before making her way up to the podium.

When ET caught up with Fassbender at the Golden Globes in January, he gushed that he was "very proud" of his stunning girlfriend.
