Joe Jonas and Sophie Turner are first-time parents after the actress gave birth to a baby girl in Los Angeles last week.
The baby, reportedly named Willa, was born on Wednesday, reports TMZ.
Joe and Sophie never publicly acknowledged they were expecting a baby, but the Game of Thrones star revealed her baby bump for the first time in public in May.
Previously, the actress hinted at her changing figure by wearing a maternity gown from designer brand Doen.
Turner and Jonas celebrated their wedding anniversary on 1 May, marking one year since they staged an impromptu ceremony in Las Vegas. They then held a more formal affair in the south of France last summer.
