Sebastian Stan and his girlfriend, Annabelle Wallis, reportedly have a new costar in life following the birth of their first baby.
According to TMZ, sources confirmed the couple officially became a family of three last month after announcing that they were expecting their first baby together in May. Us has reached out to reps for both for comment.
Stan and Wallis have been romantically linked since May 2022. The couple sparked dating rumors when they were spotted getting cozy in a since-deleted Instagram photo from Robert Pattinson’s birthday party.
In the four years since, Stan and Wallis have maintained a relatively low profile. However, the Thunderbolts star and the Peaky Blinders alum enjoyed a rare public outing at the 2025 Golden Globes, making their red carpet debut at the event. Inside, the pair shared a celebratory kiss after he won Best Performance by a Male Actor in a Motion Picture – Musical or Comedy for A Different Man. He also gave her a shout-out during his acceptance speech, gushing, “Annabelle, I love you.”
In April, news broke that Stan and Wallis were expecting their first baby after she was spotted with a baby bump in New York City. The following month, the father-to-be broke his silence on the pregnancy, telling Deadline, “I want to be a good dad.”
Stan subsequently elaborated on his shifting priorities as he prepared for first-time parenthood.
“I’m feeling the responsibility of being a good father. And not to mention a good man,” he explained in the May interview. “I’m 43 and I feel, in a lot of ways, I’m just starting to learn now. It’s just crazy to me. So, I love when I see I’m discovering different people’s point of view. I try to read as much as I can, no matter what the point of view is, just to understand it.”
Stan also revealed that his perception of manhood was changing over time.
“It’s funny, in the last couple years, I’ve started to identify sometimes being a man with just holding a plank for a very long, long time,” he said.
“Because I think it is about tolerance,” he continued. “And I think that’s something that we’re not teaching young men. We’re not teaching them how to tolerate discomfort, how to understand their own emotions, their own anger, their own frustrations. Nobody’s educating them on how to embrace depression, or being sad, feeling things, being weak, crying.”
Stan noted that his stepfather served as a role model for him due to his “quiet integrity … this quiet strength, this way of providing, this way of being there. Listening and understanding and protection as well. You’ve got to provide and protect.”
He added, “That’s kind of what I thought about in terms of what it means to be a man. And sometimes that means putting your own ego aside and looking at how you can support your family, or your loved ones, and be an example.”
Later in May, Wallis officially debuted her baby bump on the red carpet with Stan at the Cannes Film Festival. As the couple posed for photos, he wrapped his arm around her, and she cradled her pregnant belly.
