Michelle Williams welcomed her first child, Matilda Rose, with then-boyfriend Heath Ledger in 2005. Since then, she has had three more children with Thomas Kail in 2020, 2022, and 2025.
Despite her prominent roles in television and film—such as Dawson's Creek, The Greatest Showman, and Dying for Sex—Williams has kept her family life private. She avoids the spotlight when it comes to her children and has not shared much about their personal details.
"My heart obviously belongs to my children. They tug at it the most," Williams shared in a January 2023 interview with Entertainment Weekly.
In November 2022, a source told Us Weekly that Williams is "soaking up the joy" of her family life.
Michelle Williams values her privacy deeply and has successfully shielded her four children from public attention while expressing profound love for her family.
