Ewan McGregor and Mary Elizabeth Winstead privately welcome 1st child together

Ewan McGregor and Mary Elizabeth Winstead recently welcomed their first child together, a baby boy, according to two of his daughters.

On Sunday, Clara McGregor shared two photos to Instagram in which she is pictured holding her newest sibling.

"Welcome to the world little brother," the 25-year-old wrote. "Congratulations to my Dad & Mary - this is the greatest gift."

One of McGregor's other daughters, Esther McGregor, also shared three similar photos and seemingly revealed her new sibling's name.

"Met my little brother looking like a pirate. I recommend!" she wrote in the caption. "Welcome to the family little Laurie."

While this is the first child for the "Scott Pilgrim vs. the World" actress, this is the fifth for McGregor, who shares Clara and Esther -- as well as daughter Jamyan and son Anouk -- with ex-wife Eve Mavrakis.

McGregor and Winstead met while starring on season 3 of "Fargo" together in 2017, later reuniting for 2020's "Birds of Prey."

"Good Morning America" has reached out to reps for McGregor and Winstead for comment.

Disney is the parent company of Lucasfilm as well as ABC News and "Good Morning America."
