The actress completed her look with a small box clutch bag with delicate silver embroidery.

Jennifer and director Aronofsky will soon celebrate their one-year dating anniversary after meeting on the set of mother! in 2016.

The lady is a vamp: The Oscar-winning actress, 27, vamped up her typically casually look as she slipped into a tiny tube top and plunging tuxedo with unusual mesh sleeves

It’s party time: Teaming her smart suit jacket with matching cigarette pants, the American Hustle star added height to her frame with a pair of towering strappy sandals

The thriller was directed and written by Aronofsky, with Jennifer starring alongside Michelle Pfeiffer and Javier Bardem.

The couple are expected to make their red carpet debut at the premiere of mother! at the 74th Annual Venice Film Festival on September 5.

While the couple privately started dating in September 2016, Jennifer insisted they had ‘energy’ from the moment they met in an interview with the new issue of Vogue magazine.

‘We had energy. I had energy for him. I don’t know how he felt about me,’ she told the September 2017 issue, which doubles up as the 125th anniversary edition of the fashion publication.
