On Sunday, June 27, the world found out that McGregor and Winstead’s family celebrated the birth of its tiny new addition courtesy of an Instagram post made by the Halston actor’s oldest child, Clara McGregor. In the heartfelt social media post, Clara shared photos of herself holding her youngest brother (named Laurie) to the feed.
“Welcome to the world little brother,” Clara captioned the photoset, emphasizing her happiness with a heart emoji. “Congratulations to my Dad & Mary - this is the greatest gift.”
Clara's sister Ester also shared a first glimpse at little Laurie on her own instagram.
"Met my little brother looking like a pirate. I recommend!," Ester captioned her photoset of the special moment. "Welcome to the family little Laurie."
The couple has been dating since 2017, connecting romantically when they worked together on the set of the television reboot of Fargo at the time. In the year that followed, both McGregor and Winstead would terminate their respective marriages through low-key divorce proceedings; McGregor cited "irreconcilable difference" for the cause of the split from Mavrakis, while Winstead called her ex-husband Riley Stearns her "ride or die" in the since-deleted social media announcement about their divorce.
Things weren't exactly copacetic between the family when McGregor first initiated his divorce — his daughter Clara was especially unhappy with the trajectory of her parents' marriage — but it looks like the arrival of baby Laurie is bringing this brood closer together.
