Michelle Williams opened up this week about the arrival of her fourth child and gave a sweet shoutout to her surrogate. During an appearance on " Jimmy Kimmel Live! " on Monday, the "Dawson's Creek" alum confirmed she and husband Thomas Kail recently welcomed their third baby together via surrogacy.

Michelle Williams, mom to daughter Matilda with the late Heath Ledger, has since opted to expand her family with husband Thomas Kail entirely out of the spotlight while her career has been thriving.
