Jessica Chastain’s undercover romance with fashion executive Gian Luca Passi is reportedly getting serious.

The 35-year-old Oscar-nominated Zero Dark Thirty actress is rumoured to have been quietly dating Gian, an Italian senior official for French clothing line Moncler, for some time now.

Apparently the pair are smitten with each other.

"They've been dating seriously for awhile now and Gian really likes her," a source told Us Weekly magazine.

It is said that Jessica is doing everything in her power to keep her relationship out of the limelight.

Her supportive beau is of the same mind and is willing to go out of his way to ensure their affair remains private.

“He is a classy guy and completely agrees about respecting their relationship and not flaunting it," the insider said.
Jessica has alluded to Gian recently.

When asked by American journalist Katie Couric on talk show Katie whether or not she had a boyfriend, the star gave a clear answer.

"I do . . . I have a rule that I don't date actors so he's not in the business at all . . . He's in the fashion industry,” Jessica shared.
