Jack Antonoff attended Taylor Swift's wedding to Travis Kelce at Madison Square Garden on July 3 with his older sister, Rachel, by his side, amid news of his separation from wife Margaret Qualley. News of the split broke on July 9, with rumors swirling after Qualley was absent from the wedding. TMZ reported that Qualley removed wedding photos from her social media, though Antonoff was still spotted wearing his wedding ring in Brooklyn after the split was announced. Antonoff and Qualley tied the knot in 2023 after two years of dating. Qualley had previously spoken about feeling "really lonely" in relationships before Antonoff, saying in a Cosmopolitan interview that he makes her feel "safe and comfortable." The couple attended the 2026 Grammy Awards together in February, where Qualley addressed her preference for not discussing her private life, telling Vanity Fair she would "rather say nothing at all" than have someone have the wrong idea about her.
