Jake Gyllenhaal's rumored girlfriend Jeanne Cadieu attends opening of his Broadway play

Jeanne Cadieu continues to support rumored boyfriend, Jake Gyllenhaal.

Though the French model has yet to confirm her relationship with the actor, she stepped out on Thursday night for opening night of his Broadway play, "Sea Wall/A Life."

The 23-year-old looks stunning in a simple shift dress and casual updo as she posed solo on the red carpet at New York City's Hudson Theatre, while Gyllenhaal was dapper in a gray suit over a white tee as he posted alongside his co-star, Tom Sturridge. 

The rumored couple also reportedly attended the opening's after-party together.

SEE ALSO: Jake Gyllenhaal shares details of his latest Broadway run

Their outing comes nearly two months after Cadieu attended the premiere of Gyllenhaal's latest film, "Spide-Man: Far From Home," in June, where they also posed separately.

Cadieu and Gyllenhaal were first romantically connected last December, and Page Six reported earlier this week that, in addition to a recent trip to Martha's Vineyard, the "Brokeback Mountain" actor has also introduced his model girlfriend to his family, making insiders believe that they're getting more serious about their romance.

Ahead of the limited Broadway run for "Sea Wall/A Life" that started this week, Gyllenhaal opened up to AOL about his love for theater and the different way in which it allows him to connect with audiences.

"I’ve learned how much love there is when people decide to come to the theater and that the love of the theater is a very particular kind of thing. It's the love for that live experience," Gyllenhaal told us back in June. "It’s a commitment, and I consider it to be an honor every night when I get out there to perform for a large group of people who have gathered and paid for that specific thing. It’s something you don’t get when you do television or film. You never really feel that feeling, and I think that anticipation moved us into realizing how much we appreciate and love the audience that comes together."
