Margaret Qualley returned to set just weeks after splitting from her partner of three years, Jack Antonoff. The actress was photographed filming for her latest movie Possession, a remake of the 1981 horror.

The star was dressed in a black long-sleeves dress that featured a backless design, figure-hugging bodice, and breezy mesh skirt. The garment was styled with opaque tights and a pair of black heeled ballet flats. Margaret's brunette locks were styled into an undone, loose braid that fell to her hips. Her complexion was left natural and radiant with minimal makeup.

HELLO!'s TV & Film Editor, Nicky Morris, spoke to us about what fans can expect from the highly anticipated movie. "After her acclaimed turn in the gasp-inducing body horror, The Substance, Margaret Qualley is returning to the genre in Possession, the upcoming remake of the 1981 horror classic," she shared. "The original film starred Sam Neill as a spy named Mark who returns home to Cold War-era West Berlin to his wife Anna (Isabelle Adjani) demanding a divorce. Suspecting Anna of having an affair, Mark investigates – but what he finds is far more sinister. The upcoming film is directed by Parker Finn (Smile), while Margaret stars opposite Callum Turner and Paul Dano. I'm marking my calendar for this one!"

Margaret Qualley's split from husband Jack Antonoff

Margaret's appearance comes after she broke her silence on speculation surrounding her marriage to music producer Jack Antonoff. The 31-year-old actress shared a statement through her representative after reports suggested the couple's three-year marriage had become "rocky" and that they were no longer living together. 

The statement rejected claims that infidelity or a breakdown in trust had caused their reported split. However it did not confirm nor deny that the pair had separated. Speculation circulated after Jack attended Taylor Swift and Travis Kelce's July 3 wedding without Margaret, instead bringing his sister Rachel Antonoff as his date.

The former couple were initially introduced by Margaret's older sister Rainey Qualley. Eight months after meeting, the pair got engaged. Margaret confirmed the news in an Instagram post of three selfies of her and Jack, her showing off her diamond ring, with the caption: "Oh, I love him!"

Margaret and Jack tied the knot in August 2023 in the singer's home state New Jersey. "It was just so much fun," Margaret told Cosmopolitan. "I got so drunk. I've never had that many espresso martinis in my life."

The pair's last public appearance was in February 2026 at the 68th Annual Grammy Awards. The actress wore a sleeveless black silk midi dress that featured a plunging neckline and a gold zip accent on the side. The garment was styled with black heels and a monochromatic clutch.
