#11: Sebastian Stan
The one and only Bucky Barnes, Sebastian Stan, has a pretty private personal life. He’s dating Alejandria Onieva but has only made mention of their relationship once, back in 2021, though they’ve been photographed out and about several times together by fans and paparazzi.
Alejandria is a telenovela actress and recently worked on Alta Mar, a Spanish Netflix original. One of Stan’s more famous previous relationships was with fellow Gossip Girls costar Leighton Meester back in 2009. Fans were sad when they broke up, but we’d say it was for the best considering how happy he looks now!
