The expecting parents broke the news to their fans on Instagram, reported Aceshowbiz.
Scodelario and Walker, 33, are pictured kissing on the beach while cradling her growing belly. He was shirtless wearing shorts while his pregnant wife showed off her baby bump. They stood in front of a love sign drawn in the sand.
"Happy summer from the four of us.. I love you @kayascods," Walker captioned it. The actress wrote an equally sweet caption for another photo on her own IG page, "I love you @findthewalker I love our little family."
