Jessica and GIan Luca married at Gian Luca's family's estate, Villa Tiepolo Passi, in nearby Carbonera. 

Gian Luca is the co-founder of Prosecco wine company, FIOL and is also a bonafide Italian count, whose aristocratic family dates back almost a thousand years in Treviso.  

The family has lived in the palace-like estate for generations and the property features beautifully manicured Italian-style gardens decorated with beautiful fountains and statues.

Jessica's Wilde Salomé director/castmate Al Pacino is rumoured to have walked her down the aisle since her estranged, biological father Michael Monasterio passed away in 2013

Jessica, 40, met Gian Luca in 2012 while he was working as Director of Public Relations for Armani.  

'He's a gentleman,' Chastain gushed to W Magazine in 2015.

'And that's very important to me. He's from an old-school Italian family. No one in his family has ever been divorced!'

Other than those few revelations, Jessica has remained tight lipped about her relationship with Gian Luca.

'I am very, very happy,' she teased during an Extra interview in 2013. 

'It's a wonderful thing when a career does so well and your personal life goes so well.'

However, the engagement must have been a surprise as Jessica said she wasn't sure if marriage was in her future in 2015.

'I'm not quite sure of what I want in my life, and who knows if marriage is a part of it. So to me, marriage is not an important thing,' she told People.

The Cannes Film Festival juror was previously in a long-term relationship with writer-director Ned Benson that ended in 2010.
