Though Sophie Turner and Joe Jonas kept the details of Turner's pregnancy mostly private over the summer, the couple seem to be getting more comfortable with opening up publicly about their new baby girl, Willa.

In a photo posted to her Instagram Story on Friday, the Game of Thrones actress subtly revealed her daughter's date of birth. The snap captured a delicate golden chain necklace with a rectangular nameplate engraved with the numbers, "22.07.20," the date Willa was born.
