Sebastian Stan and partner Annabelle Wallis reportedly welcome first baby.

TMZ reports that the couple became a family of three last month after announcing that they were expecting their first baby together in May. The Avengers: Endgame star and British actor Wallis have been romantically linked since May 2022. The couple sparked dating rumours when they were spotted getting cosy 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. The Thunderbolts star and the Peaky Blinders alum enjoyed a rare public outing at the 2025 Golden Globes, making their red-carpet debut.
