Sebastian Stan, 43, and Annabelle Wallis, 41, have welcomed their first child, according to a new report.
The couple, who have been dating for four years, confirmed they were expecting their first child together in April. In May, they made their first red carpet appearance together amid the pregnancy news at an awards event during the Cannes Film Festival in France, where Wallis was seen cradling her baby bump.
Sources confirmed to TMZ on Monday that the couple welcomed a child last month. Representatives for Stan and Wallis have not yet responded to requests for comment.
News that the couple was expecting first broke in March. The actors have largely kept their relationship private, despite dating since May 2022. They were first seen together publicly in 2022 at Robert Pattinson's birthday party in New York City.
Stan and Wallis began attending public events together in 2024. Stan brought Wallis as his date to the premiere of "A Different Man" at the Berlin Film Festival in February 2024, and they later attended the red carpet for his film "The Apprentice" at the Cannes Film Festival in May 2024.
In January 2025, they attended the Golden Globes, where Stan won his first Golden Globe for best performance by a leading actor in a musical or comedy film for "A Different Man." During his acceptance speech, he thanked Wallis, saying, "Annabelle, I love you."
In a rare interview with Vanity Fair in April 2025, Stan spoke about the difficulty of maintaining privacy, stating that his personal life is "the one part of my life that I try to keep somewhat for myself, even though it sort of ends up being out there."
