Actor-stand-up comedian and wife Kaya Scodelario have welcomed their first child into the world, a baby boy.
Scodelario took to Instagram to share the good news, posting a photo of the baby's hand beside their French Bulldog, Arnie.
"Welcome to the world little man. We couldn't be happier or more in love with you & Arnie's loving his new cuddle buddy," she captioned the photo.
The couple first announced that they are expecting their first child in June via Instagram.
Walker shared a photo of his pregnant wife and their dog on the beach, writing, "Happy summer from the four of us.. I love you @kayascods."'
Scodelario, 24, and Walker, 34, got engaged in December of 2014 and tied the knot just before ringing in 2016.
Walker was previously married to Meryl Streep's daughter, Mamie Gummer, from 2011 to 2013.
