Jennifer Lawrence & Bradley Cooper Get to Work on 'Joy'

Jennifer Lawrence carries a mug of liquid while heading to her trailer on the set of her movie Joy on Monday (March 30) in Boston, Mass.

The 24-year-old actress’ co-star and frequent collaborator Bradley Cooper was seen on set that day as well eating a sandwich on his lunch break. It looks like there’s a bit of snow falling in Boston today!

The David O. Russell film, which reunites Bradley, Jennifer, and Robert de Niro, is about the story of a family across four generations and the woman who rises to become founder and matriarch of a powerful family business dynasty.

FYI: Bradley is wearing a Fjallraven shirt.
