Elsa is the mother of Evans' rumored girlfriend Alba Baptista; they were both snapped up by different accounts.
The photo-sharing site's description says nothing it posts should necessarily be treated as fact, so treat it with a grain of salt. At the very least, it got the Reddit community in a bit of a tizzy.
The pair began following each other and their families on the photo-sharing site earlier this year. They met through mutual friends, who we can only picture as Charlie Day from It's Only Sunny in Philadelphia.
There was also some speculation around geography, with rumors swirling about that the pair linked up in Europe when Evans was filming The Grey Man and she was filming Warrior Nun, though neither production location overlapped.
Portuguese actress Alba is best known for her role in two seasons of the Netflix series Warrior Nun, while Chris Evans has played Captain America since 2012.
