Officially, no reason has been given. The couple has not explained the split publicly, and their representatives did not immediately comment on the filing. The reporting so far covers what happened and what the sources say about the relationship, not why.
The filing was reported on Friday, October 30, 2026. AP says Margaret Qualley and Jack Antonoff filed in Kings County Supreme Court in Brooklyn, listed as an uncontested matrimonial action, with Qualley as plaintiff. People, cited by Billboard, TMZ and Complex, describes it as a joint, uncontested divorce reached by a "mutual decision." One source described the marriage as "rocky" and said the two were "figuring things out."
The split became public in July 2026, when People reported that they had separated, and both sides confirmed it. Qualley's representatives called narratives about infidelity "categorically untrue," and the press has linked the breakup to Qualley not attending Taylor Swift's wedding with Antonoff. Those links are speculation from coverage, not confirmed reasons.
Antonoff has said he will keep performing songs about the marriage from Bleachers' album Everyone for Ten Minutes. Anything beyond the court filing and the sourced accounts would be guesswork, so the couple's own statements are the place to check if they make one.
