Margaret Qualley and Jack Antonoff End Their Marriage

Margaret Qualley and Jack Antonoff are ending their marriage through a divorce filing in New York, following three years as a married couple. The case was filed on October 30 in Kings County Supreme Court and is listed as uncontested. The filing identifies Qualley as the plaintiff, with Antonoff named as defendant.

The two started a relationship in 2021 and wed in New Jersey in August 2023. They separated in July, court information states. Their last public appearance together was at the Grammy Awards in February 2026.

People familiar with the couple described the split as not arising from a dramatic incident and said the two were working through it together. One person said Antonoff could be particular about how things were done, and that Qualley sometimes felt her views did not receive equal consideration. Another account cited their demanding schedules and time apart as factors in the breakup.

The pair had continued trying to repair the marriage months before the separation, but those efforts did not succeed. Qualley and Antonoff have not publicly commented on the filing. They were engaged in 2022, after Antonoff proposed in Paris.

Qualley, 32, is an actor whose credits include “The Substance” and “Once Upon a Time in Hollywood.” Antonoff, 42, is a Grammy-recognized music writer and producer, collaborating with Taylor Swift, Lana Del Rey and Sabrina Carpenter. He also performs with the band Bleachers.
