Williams is already mom to 14-year-old daughter Matilda, whom she shared with the late Heath Ledger.
Kail and Williams previously worked together on her FX series, Fosse/Verdon. News of the pair's relationship comes less than a year after the actress' split from musician Phil Elverum; the pair married in a secret ceremony in the Adirondack Mountains in 2018, and broke up in April.
During a 2018 interview with Vanity Fair, Williams opened up about how she speaks to Matilda about Ledger's death and discussed moving on romantically.
"When you’re a single parent, and that element of provider and protection is missing, it’s scary," she admitted.
"I always say to Matilda, ‘Your dad loved me before anybody thought I was talented, or pretty, or had nice clothes,’” she said, adding, “I never gave up on love.”
