Jack Antonoff and Margaret Qualley have reportedly separated just months before their third wedding anniversary. An insider told People that the relationship had been "rocky" for some time and the couple was "trying to figure things out." Signs of trouble include Qualley changing her Instagram handle from one referencing Antonoff's song "Isimo" and deleting photos of him from her account, though she later unarchived some. Qualley also did not attend Taylor Swift's wedding with Antonoff on July 3, fueling split rumors. Antonoff attended with his sister instead. Additionally, the Bleachers frontman removed the song "Margaret," inspired by Qualley, from the band's tour setlist. The couple, who started dating in 2021 and married in August 2023, have not publicly commented on the separation.
