Jessica Chastain is an independent woman! Echoing comments recently made by fellow actress Mindy Kaling in Good Housekeeping’s February 2015 issue, the 37-year-old Interstellar star says she’s not sure if she’ll ever tie the knot. “I’m not quite sure of what I want in my life, and who knows if marriage is part of it,” she says, “so to me marriage is not an important thing.” Chastain has been dating Italian fashion executive Gian Luca Passi de Preposulo since 2012, and “everything is fantastic,” she tells People in its Feb. 2 issue, on stands Friday.
