Dressed in costume (red dress, blue apron, dark tights and shoes), the baby-bumpin' Brit beauty was spotted walking around the outdoor U.K. set in between takes. Blunt will play the Baker's Wife in the highly anticipated movie adaptation of Stephen Sondheim's Broadway musical of the same name.
Blunt and Krasinski announced their baby news earlier this month.
Also snapped on set was Blunt's costar Chris Pine, who was dressed regally in costume to play Cinderella's Prince. The flick's Cinderella, Anna Kendrick, was also filming scenes on set in a gorgeous white period costume dress.
Kendrick tweeted a pic of her director's chair with the name Cinderella on it, writing, "Weird." She also shared a magical photo of the woods where they are filming with the caption, "The way is clear, the light is good...." #IntoTheWoods."
