US-ENTERTAINMENT-OSCARS-FOREIGN LANGUAGE FILM AWARD RECEPTIONJust call her Countess Jessica Passi de Preposulo-- even if she'll never call herself that, officially.

Jessica Chastain married Gian Luca Passi de Preposulo this past weekend at his family's Italian estate north of Venice. According to People, the Passi de Preposulo family is one of the most noble in Italy, dating back to the year 973. (And they make their own prosecco.) The family still reportedly uses their count and countess titles, even though the Italian aristocracy is no longer recognized by the government. It's still a cool name-only title.

The wedding had a seriously swanky guest list, including Chastain's friends and co-stars Edgar Ramirez, of "Zero Dark Thirty," Anne Hathaway of "Interstellar," and Emily Blunt of "Snow White and the Huntsman."

Check out People's wedding photos, showing Chastain's beautiful dress and her arriving guests.

Jessica's new husband works in high fashion, currently for the French fashion brand Moncler. Chastain is usually very private about her personal life, but she has posted a few loving shots with her man in the five years they've reportedly been together.

So happy to be together on your birthday! ❤ Thankful for real life. ❤
