Fans might not know that based on his public appearances, however, as Stan tends to keep his relationship with girlfriend Alejandra Onieva extremely under wraps.  

He did praise her in a rare social media post in June 2021, writing, “Over a year ago, out of a lot of darkness… you became the light ???? I’m so grateful,” alongside a very sweet and funny video illustrating how much she means to him.

After offering fans such an adorable peek into his real-life relationship, it’s understandable if you want to know more! So here’s everything we know about Sebastian Stan’s real-life love, girlfriend Alejandra Onieva.

Yes! Stan is dating Onieva and seemingly has been for nearly two years; the pair were first photographed together in summer 2020. 

Onieva, born in Madrid, is a Spanish actress who has appeared in several films made in her home country, including Nueva Tierra, For a Handful of Kisses and Stories Not to Be Told.

She also had a primary role in the Spanish-language Netflix series High Seas, about two sisters who get wrapped up in something mysterious and disturbing aboard a luxury ship traveling across the Atlantic in the 1940s.

It’s unclear exactly how long the pair have been together, although they were first linked in summer 2020 when they were spotted holding hands in New York City.

Onieva sort of made their romance Instagram-official when she shared a pic on December 7, 2020, captioned “Walking on a Dream.” It showed the two of them in shadow.
