Margaret Qualley and Jack Antonoff have split after nearly three years of marriage, according to reports. Sources close to the couple told People magazine that the pair have separated and are currently navigating a "rocky" relationship, with a second insider stating they are "figuring things out." Margaret Qualley and Jack Antonoff, pictured in February 2026 at the Grammys, have reportedly split after nearly three years of marriage. The announcement of their separation comes just days after Antonoff attended Taylor Swift and Travis Kelce's July 3 wedding with his sister, Rachel, instead of Qualley. This public appearance fueled speculation about the state of their marriage. Further contributing to the speculation, it recently emerged that Qualley had quietly deleted photos of the couple's August 2023 wedding from her Instagram account. A review of her Instagram feed shows no photos of Antonoff, including those from their wedding period. Her most recent social media post acknowledging her husband was a birthday wish on her Instagram Story on March 31. In March, Qualley had shared throwback photos from their 2023 wedding to promote Antonoff's Bleachers single "Dirty Wedding Dress," which referenced their nuptials. These photos are no longer visible on her main feed, though a fan page reposted them. On April 28, Qualley changed her Instagram username from @isimostar to @sarahmargaretqualley23. The previous username was notable as Antonoff has a 2024 song titled "Isimo" with his band Bleachers. Antonoff and Swift have collaborated on ten albums and several singles. Qualley's absence from the July 3 wedding also followed an earlier instance where she appeared hesitant when asked about her husband's production work for Swift. During an interview on The Today Show, when a co-host mentioned Swift's album "The Life of a Showgirl" and Antonoff's role as producer, Qualley responded that she "don't know anything" and would be "excited to listen to the music." Antonoff has been a primary collaborator and producer for Swift on albums such as "Midnights" and "The Tortured Poets Department." The couple, who were romantically linked in 2021, became engaged the following year. Swift fans had previously garnered attention for swarming Qualley and Antonoff's wedding rehearsal dinner in 2023. Qualley and Antonoff's last public appearance together was at the Grammy Awards in February 2026, where they were photographed displaying affection.
