Sebastian Stan, 43, and Annabelle Wallis, 41, have welcomed their first child together, according to a report from TMZ.
The couple, who have been dating for four years, confirmed they were expecting in April. They made their first red carpet appearance as a couple during the Cannes Film Festival in May, where Wallis proudly displayed her baby bump.
Sources confirmed to TMZ on Monday that the child was welcomed last month. Representatives for Stan and Wallis have not yet responded to requests for comment.
The news of their pregnancy first emerged in March. Stan and Wallis are known for being private about their relationship, having remained discreet despite dating since May 2022. They were first publicly seen together in 2022 at Robert Pattinson's birthday party in New York.
Their public appearances increased in 2024, with Stan bringing Wallis as his date to the premiere of "A Different Man" at the Berlin Film Festival in February. Three months later, they attended the Cannes Film Festival for the premiere of Stan's other project, "The Apprentice."
In January 2025, the couple attended the Golden Globe Awards, 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."
Stan previously dated Leighton Meester from 2008 to 2010 and has been linked to Dianna Agron, Jennifer Morrison, Margarita Levieva, and Alejandra Onieva. Wallis previously dated Chris Pine for four years until their split in March 2022.
