Michelle Williams became a mother for the first time in 2005, when she and her then-partner, the late Heath Ledger, welcomed their daughter Matilda Rose. Fourteen years later, Matilda reportedly helped her mother meet director Thomas Kail, with whom Williams secretly married and had a son named Hart in 2020.
Williams and Kail later expanded their family, welcoming two more children in 2022 and 2025. The names, genders, and birthdays of those younger kids remain private, as Williams prefers to keep her family life away from public attention.
Although she is widely recognized for major roles in television and film—ranging from Dawson’s Creek to The Greatest Showman and Dying for Sex—the actress prioritizes her home and children over fame. She has consistently protected their privacy and rarely discusses them publicly.
“My heart obviously belongs to my children. They tug at it the most,” Williams said in a January 2023 interview with Entertainment Weekly.
In November 2022, a source shared with Us Weekly that Williams was “soaking up the joy” of family life, highlighting the happiness she finds in motherhood.
Michelle Williams, known for her acclaimed acting career, treasures her private family life with four children, keeping their world peaceful and away from the spotlight.
