Yes, Sebastian Stan is currently in a relationship. He’s been dating British actress Annabelle Wallis since around mid-2022. Though it started quietly, the couple has gradually become more public—stepping out together at events like Cannes and the Golden Globes. In fact, at the 2025 Golden Globes, Sebastian dedicated his award to her with a heartfelt “Annabelle, I love you” during his acceptance speech. Their relationship remains relatively private, but their occasional red carpet appearances and film premiere support make it clear they’re happily together.
