OK, not really, but this very private pair did allow themselves to flaunt a little bit of PDA during the 2016 Golden Globe Awards.
The Danish Girl actress was seated next to her beau, and the couple showed some sweet and innocent admiration for one another when Fassbender heard his name get called as a nominee for Best Performance by an Actor in a Motion Picture-Drama for his work in Steve Jobs.
At one point, Vikander turned to Fassbender, who was smiling from ear to ear, and gave a loving and supportive rub on his back as they both awaited the announcement of the winner (spoiler alert: It was Leonardo DiCaprio).
E! News' Marc Malkin recently caught up with Vikander on the red carpet at the Palm Springs International Film Festival, and the beauty dished that she spent her New Year's Eve enjoying a low-key night in with her "casual" yet confirmed boyfriend, Fassbender.
"It was not a very, very late night because I had to fly here, but we had a grill going, cooked some pasta, made a good dinner, watched some fireworks," she told us. "We counted down until midnight. It was great!"
And in case there was any question as to who she locked lips with at midnight, Vikander said nonchalantly, "I think I kissed my boyfriend."
