There are some stars who seem to be an open book, like Heidi Montag, (who just shared her most recent 3D sonogram pic!) or Selena Gomez, who says she keeps it real regarding her relationship with The Weeknd.

Then, there are others who like to keep things a little more鈥 private. The Zookeeper鈥檚 Wife star Jessica Chastain definitely falls into the latter category, keeping a relatively low profile when it comes to her love life: You鈥檒l be hard pressed to find a PDA-packed pic of her longtime BF Gian Luca Passi de Preposulo. Actually, make that husband, since the two have just tied the knot!

The 40-year-old redhead made things official with her 34-year-old beau, who she鈥檚 been seeing since 2012, today in a destination ceremony. The proceedings culminated at Passi de Preposulo鈥檚 family estate, an Italian villa that has been in his family since the 1800s and rests an hour north of Venice.

With famous faces such as Anne Hathaway and Emily Blunt reportedly in attendance (and possibly in the bridal party!), the twosome walked down the aisle to say their 鈥淚 dos鈥 after spending half the week in Passi de Preposulo鈥檚 native country 鈥 guests arrived to Venice on Wednesday to take in the sights before the big day.

While official photos have yet to be released, we鈥檙e excited to hear the happy news nonetheless. Here鈥檚 wishing them all the very best!
