Michelle Williams and Husband Thomas Kail’s Relationship Timeline

Michelle Williams and Thomas Kail's relationship got off to an unconventional start — but the duo are still going strong. The couple crossed paths while working together on FX's Fosse/Verdon. During filming, Williams was married to musician Phil Elverum, from whom she split in April 2019. Kail, for his part, was married to Broadway's Angela Christian. However, sparks seemingly flew between the Dawson's Creek alum and Kail on set. Us Weekly confirmed in December 2019 that the pair were engaged — and that Williams was pregnant with their first child together. Williams previously welcomed daughter Matilda in October 2005 with late partner Heath Ledger, from whom she split in 2007. Ledger died of an accidental overdose the following year. Williams and the In the Heights director were "very happy and thrilled to be bringing a baby into the world," a source told Us in January 2020, adding that the twosome "would like to be married" before she gave birth. The pair tied the knot later that year and welcomed their first child in June 2020. Scroll down to relive Williams' private romance with Kail:

Fosse/Verdon was in production from late 2018 to early 2019. Kail directed Williams in a handful of episodes, earning him an Emmy nod. 

Less than one year after they quietly tied the knot, Us confirmed Williams' split from Elverum. Kail ended his marriage to Christian the same year.

Us confirmed the Blue Valentine actress' engagement to — and first pregnancy with — the Tony winner.

The duo made their red carpet debut as a couple at the 2020 Golden Globes, attending the SAG Awards together weeks later. At the time, a source told Us that the beginning of the pair's romance was "messy behind the scenes." 

Us exclusively confirmed Williams' secret wedding to Kail after the twosome were spotted wearing matching rings.

The Venom star gave birth to the pair's first child together. Two years later, Williams revealed the baby boy's name: Hart.

The Golden Globe winner revealed she and Kail were expecting their second child together, her third. "It's totally joyous," she gushed to Variety at the time.

The pair stepped out with their newborn and eldest son, Hart, in New York City, confirming they were officially a family of five.

Kail supported his wife at the 2023 Academy Awards, where she earned a nomination for Best Actress for her work in The Fabelmans.

Williams supported her husband at the 2023 Tony Awards. Kail produced and directed a Broadway production of Sweeney Todd, which was up for Best Revival of a Musical.

News broke on April 3 that Williams and Kail welcomed their third baby (her fourth) via surrogate roughly six weeks prior.

Williams confirmed the birth of her and Kail’s third child during an appearance on Jimmy Kimmel Live!

“This last baby did not come out of my body,” she told guest host Tiffany Haddish before giving their surrogate a shout-out. “The miracle of our little girl is thanks to Christine. Thank you, Christine!”

“I have, thanks to Christine, three under 5 at home,” she continued. “Everything’s good and under control. I’m the adult. It’s good, it’s good. It’s just really busy. I’m just trying to figure out the life-work balance, and you know, I hear a lot of people talking about self-care, and I’m just wondering, ‘When?!’ Because I’m a working mom, and so I already have the guilt and I don’t want to take more time away from them, but I understand I need to fill up the tank.”

Kail brought Williams as his plus-one to the New York City premiere of Hamitlon in honor of the Broadway show’s 10th anniversary. The couple were all smiles as they walked the red carpet.
