On Saturday, the 40-year-old actress said "I do" to longtime boyfriend Gian Luca Passi de Preposulo in a ceremony held in Treviso, Italy. Chastain looked absolutely gorgeous in a custom-made strapless gown that she paired with a simple updo and a long white veil. As for the 34-year-old groom, he wore a dapper blue suit. A few of Chastain's famous friends attended the ceremony, including Emily Blunt, Anne Hathaway and Chastain's Zero Dark Thirty co-star, Edgar Ramirez.
The couple reportedly started dating in 2013. Passi de Preposulo's noble family reportedly goes back 1,000 years in Bergamo Alta. His father, Alberto Passi de Preposulo, uses his "Count" title, though the Italian aristocracy is no longer recognized by the Italian government.
Chastain's big day comes just a few weeks after Kate Middleton's sister Pippa married her longtime love, James Matthew, in Europe. Check out her wedding dress:
