Actress Michelle Williams has welcomed her fourth child, her third with husband Thomas Kail, via surrogate, PEOPLE reports.

The couple, who have kept their personal life private, were spotted around their New York neighborhood with their newborn, who arrived six weeks ago.

A source close to the couple shared, "They couldn't be happier to expand their family, and Matilda has been doting on her younger siblings." Williams, 44, is already a mother to Matilda Ledger, 18, whom she shared with the late Heath Ledger, as well as two young children with Kail: Hart, 4, and another child born in 2022.

Williams, best known for her work in The Fabelmans and Brokeback Mountain, has been balancing motherhood with her acting career. She recently took a hiatus after The Fabelmans and is now making a return with the upcoming Hulu limited series Dying for Sex, which premieres on April 4, 2025.

In a 2023 interview with Entertainment Weekly, Williams spoke about juggling career and motherhood, saying, “My heart obviously belongs to my children; they tug at it the most. But I really want to be able to have both.”

Williams and Kail, a Tony-winning director known for Hamilton, have been married since 2020. While the couple has yet to make an official statement, their growing family is clearly thriving.
