Michelle Williams is a mom of four.
The actress, 44, quietly welcomed her fourth child, and third with husband Thomas Kail.
The family was spotted in their New York neighborhood, with a source telling People that the couple welcomed their newest addition via surrogate six weeks ago.
“They couldn’t be happier to expand their family, and Matilda has been doting on her younger siblings,” the insider shared.
The Post reached out to Williams rep for comment.
Williams is also mom to daughter Matilda, 18, with the late Heath Ledger and shares son Hart, 4, and a third baby born in 2022 with Kail, 48.
The news comes on the heels of Williams and Kail stepping out together for the New York City premiere of the star’s new Hulu’s show “Dying for Sex” on Wednesday.
Williams – who nabbed the lead role in the dramedy – wore a lavender chiffon gown, while the director donned a classic black suit.
The couple tied the knot in 2020 after meeting on set of the limited series Fosse/Vernon in 2018.
In 2022, Williams and Kail were expecting their third baby, with the actress taking a moment to gush over her pregnancy.
She told Variety at the time, “It’s totally joyous.”
The “Showing Up” alum continued, “As the years go on, you sort of wonder what they might hold for you or not hold for you. It’s exciting to discover that something you want again and again, is available one more time. That good fortune is not lost on me or my family.”
A year later, Williams got candid on taking on the starring role in “The Fabelmans” after giving birth to her third child.
“My heart obviously belongs to my children; they tug at it the most,” she shared. “But I really want to be able to have both. And I think that it requires deep thought and learning and the support of other women to figure out how to get through it.”
After becoming a family of five, a source told US Weekly how Kail had become a constant presence in Matilda’s life throughout the years.
“Matilda is a very mature and intelligent young lady,” the insider revealed in 2022. “They wouldn’t change a single thing about their life together.”
